This video has no loud heavy-metal guitar, no mirrored shooting glasses,no expensive logo jackets, no young ladies dressed in clothes that would leave them shivering in actual outdoors conditions, no screaming and cursing, just carefully-done testing that is verifiable and fairly repeatable. Thank you, Giles, for being one of the rare adults to make an airgun video for grown-ups!
.177 is faster and has a flatter trajectory and here in the USA there's no FAC requirement for airguns of any type.😁 My .177 Diana 34 puts out close to 15ft lbs with average weight pellet and close to 17 ft lbs with a slower but heavier one like the 10.5 Crossman. I'll take faster and flatter any day esp when dinging nuisance chipmunks, those things sit still like a 5 year old with ADHD and run like Usain Bolt...
I had to watch this twice and rewind a couple of times but it was worth it, Well done and a great video. It's people like you buddy who take the time and effort to make these vids to educate all of us out here. Keep up the good work my friend and keep them coming.
Most or at least many of us wonder about research and test result but do nothing about them except hope "someone" would do it and explain the why and how of it all. Kudos to you for your perseverance and obvious love of the sport. Keep up the good work.
Outstanding! This is what I have always wanted to test since I tried to work out what caliber to choose for my first 12 fpe air rifle when I was 16 in 1979. I chose a Feinwerkbau Sport .177 on the basis of a magazine review by an American hunter of African Big Game, used to handling .577 Nitro & .458 WM who was shooting rats with one, on his riverside mooring. I still have the old Feinwerkbau, but I'd knackered it in 10 years of heavy use. I'd rather buy a new HW97 .22 than get the FWB restored now. You are inspiring me to get back into airguns after years of full FAC firearms. Congrats on being one of the most watchable & charismatic shooting pundits this side of the legendary US YT great, Hickok45! I am now a new subscriber.
Hey Giles, I am a scientist and I thought your experiment was sound and has yielded some great findings. It backs up what I thought, explains why AA Field 16 grain are similar in trajectory to the lighter and faster Daystate Li 14.3 grain. Excellent job mate. Jonny
why not match a ten grain.177 pellet to a 10 grain ,22 pellet then see what calibre performs best using to identical make rifles in both calibres at the sub twelve foot pounds British limit, that would be interesting to see !
I finally found the video that I was looking for in determining the pellet speed differences between .177 and .22 at various downrange distances. Your results were contrary to my speculation... but seeing the chronograph results I have to go along with your data. I am thankful that you actually set the chronograph at the various distances to measure the pellet speed at the various distances and not calculate the pellet speed based on the ballistic coefficients and the distances of the pellets. Looks like you've put a lot of thought and time in making this video. I learned something new today. Thanks.
Great video Giles. Thanks for taking the time to get all the data and prep the video for us. I have found that your findings match mine in real life vermin control. I was finding that jacks and crows were some times not fatally shot when using JSB Exact at just shy of 50 mtrs. Respect for quarry got me to move to the JSB Exact Heavy and this has been much better. This is .177 sub 12 fpe btw.
great job on the charts, i have some charts and talks about the subject scattered some where on my youtube channel, the .177 is a ping pong ball in ballistic coefficient, high speed and energy short lived while heavy pellets are like baseballs retaining lots of wallopy down range, in general heavy objects retain more energy then light objects, i have done the 25 yard chrony test on hundreds of pellets, you can cheat a little with knowing the ballistic coefficient of pellets done at 25 yards and then use a little math to finish it out to 100 yards, a light wad cuter in .177 would be for a example 7.0 gr .010 b.c. value and a jsb 10.34 grain .030, just looking at the numbers you see that the jsb is 66% more efficient at velocity retention and it means at long distances the wad cuter will slow down quickly and have hardly any energy to spare, many occasions a heavy round nose will even reach the target first at longer ranges, the high velocity marketing in america has fooled some to think alloy pellets are fast, this is true but only to 25 yards, after that they have a dramatic loss in energy and velocity, so for longer ranges heavy pellets are faster, think of the rabbit and the turtle story, the slow turtle catches up while the rabbit sleeps, light pellets sleep and heavy pellets carry on, its just the opposite of what we think, light pellets are for close range 0-25 yards, medium pellets are for medium range 25-40 yards and long range are the heavies 40-100+ yards if possible, many people associate lighter weight with a fast trip but they forget air resistance that a lighter pellet just cant handle of the shape like a flat nose, pointed are ok but round is just a little quicker, thats why our jets went from pointed nose to more of a round nose, many like to keep pointed pellets around 30 yards and at 800 fps and under since it can be a bit picky, this is why the 25 cal springers do so well with pointed pellets due to a drop in velocity just right for a pointed pellet, where as round nose pellets that are long and heavy seem to not fuss at higher speeds and loves all distances
Being brand new to air rifles and the safety involved in safely enjoying my new hobby I came across your video's and channel. You sir are very good at teaching a novice. I have learnt so much from your informative videos. I also like your delivery. Of course, I subbed you. Once again, thank you for all your hard work and dedication to this matter, I am very grateful and you've made me a smart and safe user of an air gun.
Nice one giles. Your findings apply to all projectiles. The heavier slower moving projectile will lose less energy than the smaller faster moving ones. I'm a keen airgunner but I also have rim and centre fire rifles as well. Recently I was given a lesson in balistics by my local balistic "Yoda" who explained to me when I was considering trying a 40 grain bullet as opposed to my usuual 55 grain one why the 40 grain bullet, although intialy travelling much faster would, as the range increased, drop off and loose energy much faster than the 55 grain bullet. Thanks for taking the time and putting in the effort to prove it.
Thanks Big Fella, as always an entertaining and informative video presented in an easily digestible format. There are a lot of people that could have put the same science out there as a cure for insomnia! Keep doing what it is you do so well and good luck!
Great info and I like the dry wit thrown in for entertainment. I've often thought of doing this, but didn't want to risk my chrony. Coming from a lifetime of firearms shooting, this just confirmed what I know to be true. Heavier projectiles of the same caliber retain velocity and energy better than lighter ones do at the same distances. Heavier projectiles also have a more pronounced curve to their trajectory, so the trick is to find the tradeoff between flat trajectory and retained energy that works for your needs. Flatter shooting pellets give you more leeway in regard to aiming as well. There is a thing called Point Blank Range. This is the distance range where you can hold dead center of your target and not have to worry about hold over/under. My .177 cal. Beeman R9 for example, throws Crosman Premier Heavy pellets weighing 10.58 grains downrange starting at 747 fps. Zeroed at 15 yards and shooting at a 1 inch target, this gives me a Minimum Point Blank Range of 11 yards and a Maximum Point Blank Range of 38 yards. Anywhere within those distances, I can hold dead on the target and know I'll hit within that 1 inch target. The trajectory starts out a couple inches low at the muzzle due to the distance between the center of the bore and the center of the scope, climbs to a half inch low at 10 yds, continues to zero at 15 yds., then continues to rise to a half inch high at 25 yards, then starts falling back through zero at about 34 yds and back to a half inch low at 38 yards. That doesn't take windage into account, so there's always that variable, and even vertical impact can be affected by the wind. Those numbers are what I can do on a calm day, so I generally try to stay a couple yards shorter than the maximum to be safe. This 15 yard zero gives me the most useful range for my needs. With lighter 7.97 grain Crosman Premiers a 15 yard zero yields too high a trajectory path at midrange of nearly an inch high. I have to move my zero out to 20 yds to stay within a half inch of point of aim, and the min and max distances shift farther away by a couple of yards.
my hw110 is at 10.7ftlbs @ the muzzle....... i recently took a long ish range rabbit with a headshot in the field. i marked my point, and the rabbits point and ran to get my measuring tape. using 16g .22 i had this kill at 58m. i was comfy with the shot as id practiced my ranges and hold over/under. but i dont think id attempt any further. i remember as a kid having a pistol that shot at 4ftlbs, and i used it for point blank shots when dispatching mixy rabbits. so, your experiment with having 4-5 ftlbs down range at 50 meters seems about right with my experience. im glad someone has done the experiment to prove my theory haha! thanks again.
This is the best demonstration on pellets I have seen ever. Thank you man. I have decided to try piledriver .177 at 21 grain with my RWS 350. I hope the combination of high power and heavy pellets along with some bullet lube should help my range dramatically
Wow this video is 3yrs old & underrated. You’re an impressive & professional presenter keeping things very interesting, humorous, clear, concise, informative, & unbiased. Excellent work investing in the equipment, filming, compiling the data, delivering the info, & thoughtfully wearing the same dirtied outfit. I’m more interested in long range shooting myself & subjectively, I feel like .177 is easier to hit a target at long range when I use a lightweight alloy pellet, the Gamo Raptor, compared to when I use the same exact gun (Beeman RS2) chambered in .22 using RSW Superdomes but maybe they are both traveling the distance but I need to compensate more for the drop from the .22 & because my scope was adjusted for the .177? If you’re still making videos, would love to see a video comparison of exactly how far (distance) pellets of each caliber (same make/model) can travel before dropping & also another test to see the difference in muzzle velocity & velocity down range if an equally heavy .177 pellet & a wider .22 weighing the same w/ similar shape were fired.
Wonderful and beneficial project! I don’t think people really appreciate the work, time and effort an analysis like this took! Plz ignore any negative comments from those that can’t or wouldn’t do as such. I’m now subscribed!
Well done Giles. A bit of info I've wondered at for some time but don't have the equipment, time, patience to figure out. Thanks for your hard work to give us the answers, haven't seen this done as yet, again well done. Cheers!
Great job, thanks for putting all of the work into this video. I have been told numerous times that I was shooting too heavy of a pellet in my videos and I should shoot this brand and weight or that brand and weight. I know how my rifles shoot, and I've always felt that I was delivering plenty of energy and accuracy with my choices. When you connect on a breast shot on a dove from 153 yards and it sounds like it was hit with a baseball bat, you know what pellet your rifle prefers. Thank you again sir (you have helped me prove my point to the trolls)
Thank you for this great video! I got my Hatsan yesterday, and today my family( wife and two little girls) had great day shooting on targets. Greetings to you, especially to your wife :-)! Thank you man!
Fantastic testing and comparison of thos calibers - but....interesting would be how acts a .177 pellet with the same weight as a .22 caliber pellet!?!?!! For example a .177 JSB Exact "Monster" with 13.43 grain or a "Beast" with even 16,2 grain!!!
great video thanks for the information . that had to take time I have been testing my Diana 48 in 177at 10 feet shooting a10.65 gr Baracuda power 803 average fps 14.91 FPE have a whole box different brands an weights of pellets to test welded up a pellet trap have 10 yards in basement this summer move outside I love springers, I believe I have watched all your springer videos well this old man saying good night an GOD bless from the USA
good testing, appreciate the effort! your data is fine for the UK and lower places near a large body of water. you're basically near sea level with a high humidity. thick air made thicker with humidity. i know you've been out to Arizona a couple years ago, get a kilometer or so above sea level, and 5-10% humidity, thinner air with less dense air due to water vapor. i'm just 20 miles SW of chicago, 245M above sea level and far enough from the lake that it's usually not that humid. 4-5 months of the year (fall-winter) the humidity in my condo falls below 20% (forced air heating, gas powered). then there are all sorts of pellet designs, flat heads, pointed, domed, hollow points, hollow points with points in the hollow, etc. but i think you've laid a good baseline for general performance.
a pleasure watching. no cheap comicbook fantasy leaders, no crappy overblown music. just good clear facts. enjoyable. and... i learned something toboot! Thanks. nice job.
Great video, when i was younger and shot a lot at a club, we used Ballistic gel at 50 yards (sorry feet and inches guy) noted the depth of the pellet and then placed blocks of gel at 60 yards and 70 yards and it depended a lot on the weight of the pellet
great shooting and lots of work but I say this 22 or 177 in the head its dead and my self have used nothing but 177 for 50 years and it kills very well and unless I can shoot in the head no shot move on to another head shot great video Giles and lots of hard work well done
Years down the road Giles still scores with this interesting and informative video. Many thanks. I always enjoy your vids; a little humor and a good info!
Great work....what if we stand up and shoot an object near ground with a .22 tx200 @ 20-50 meters....is there a significant change in trajectory on .22 vs .177? Thank you
thanks for this video Giles as a new air gunner I found this very interesting and keep up the good work I really appreciate the videos and I'm glad you've carried on after the Christmas competition incident thankyou Giles
Wow, this is incredibly interesting! I had already hypothesized that lighter pellets would slow down faster, but seeing it actually come true is amazing.
well all i can say to that is if you want to give a rabbit a headache before tea then use a .22 pellet otherwise stick to .177 for the kill :) it's a no brainer lol
Correct me if I'm wrong but my takeaway from this is .22 and .177 are more alike from a practical hunting standpoint. Their is greater difference between light and heavy pellets in the same caliber than between the calibers themselves. As for hunting my - limited - research came up with a working minimum of 12 foot pounds. Lesser foot pounds calls for much more precise aim. So with 12 fps you have to hit a quarter sized target. With around 10 fps you have to hit a dime sized target (US currency). Basically the dime is around half the diameter of the quarter.
Thank you for doing this, the question came up and here it the video. Brilliant. Years ago I read in a Airgun Magazine from England that 8.44g is the best pellets for 177 Springers and you just proved it again. I am sure if you use a 470cm barrel as apposed to the 370cm, the 177 will even proof to be the better hunting pellet over all.
Best pellet test vid, nice N easy. I generally use H&N FTT for .177 in calm conditions and JSB Heavies in breezy weather. In .22 RWS Hobby's up to 35-40 yards and then any of these AA Fields, JSB Exact and Logun Penetrators any further.
great effort has been made to bring all these data. I wanted to know the trajectory results in terms of fps and muzzle energy. i got the results. Thanks.
Great video brother I just got my first 22 Cal BB gun an I have 9 ,177 Cal thank you for your helping me understand the difference much respect from Hamilton Ontario Canada 🇨🇦✌
I could potentially add that a heavier pellet may have a bigger arc to its flight, making it slightly harder to judge these things at varying distances... Where a lighter pellet may be beneficial at long varying ranges?
Giles,good video.Thanks for the hard work. The way things are going in the U.S.,we may only have air rifles too,but we may not have lead to shoot in them. Wayne
Best airgun video I've seen on ballistics in quite a while. Thanks for taking the time to do it I know it's a pain in the butt. If we all had 100 yard indoor ranges everything would be great. But if you using your rifle for hunting you gotta make those dope adjustments in the field. Here in the states Gamo Loves to use their feet per second As a selling point especially with their aluminum ammo. And it just doesn't hold up. I have two Gamo air rifles Big cat 1400 in 177 Calibre and the Gamo Hunter Extreme SE in 22 caliber. Both rifles deliver on Power and accuracy with the right pellet. I am sold on h&n baracuda Hunter Extremes. The speed is much lower But the impact is impressive. I'm using jsb exact heavy Diablos in my 177 caliber Daisy 880 multi pump. At 50 yards I'm still on target. Not a lot of muzzle energy out of that rifle but for small birds or squirrels completely adequate. My HATSAN BT65 QE PCP Air rifle is not as picky. It will take an 18 grain jsb exact heavy Or a H&N 22 grain barracuda and slam it through two inches of hardwood at 50 yards.
This video does show that the BC of the JSB exact jumbo 22 caliber 15.89 grain pellet is 0.0227 . Out of a Walter LGV master pro airgun . If you enter this BC number in chairgun with the muzzle velocity of 553.5 the number he has work out at every meter . Great work on the video .
Excellent analysis, thank you. I use Zan slugs in 177 - 10gr in my sub 12, usually up to 40m for rabbit hunting and they stop the prey instantly, with a very nice thud too. The 10gr Zan slugs fly slower than the 10.34gr JSB Hades and Exact Heavies but seem to have much less drop over the distance, about 5cm less drop.
Great video fella, can't beat getting out there and getting real physical results!! Thankyou for making the effort bro, this has helped me decide upon my next rifle, thumbs up, smiley face etc pmsl
Well done, Giles. I did not expect that. As always, your videos are both fun and educational. Thank you. Karl P.S. The picture is of my wife, not me. :>) Oh, and please don't stop cranking them out.
Good science. I would prefer it, if you added two extra columns to convert ft/s to m/s. And maybe two more to give ratios of current_speed/maximum_speed. Same for converting kinetic energy to joules. It is irrelevant if you smell, we can't feel it.
As a nuclear physicist and a military ballistics engineer, I can definitely say you have it all wrong however I totally enjoyed the video presentation just the same. Tis' a damned shame I have to search across the pond to get these kinds of stats since nobody here in the states can seem to take the time/effort to do this kind of work for those of us who enjoy a wonderful day out shooting our air rifles, pistols, revolvers and the like. Thank you mate for a great video.
@James: you beat me to it; hat tip. One would think if Bo was going to write so many pointless words after telling someone he was "all wrong" he could have at least included a reason or two.
@James I know this is an old video but I've just stumbled across it and thanks for all the work. Very good information. I hope Bo Hector was just kidding because your methods and findings look real good to me, an engineer. Here in The States I'm just starting to experiment at grouping .25 cal at 100 yards. So far I've had the best results with 25gr pellets only because at those ranges I'm running out of dots in my scope. Really enjoy your video and find them very informative. Thanks
Nicely done. :) Results are completely expected. Air resistance increases to the square of speed increase, therefore, placing the gun's energy in speed rather than in the mass, causes a larger loss of energy over distance. Energy = Mass X Velocity X Velocity (E=MV²)
Excellent information saved me hours of work, But came to the conclusion a while ago now that a heavy 177, e.g. bisley magnum 10.2 gr will hit harder, fly flatter, than a light weight 22 by just looking at the 6mm exterior ply backing the target. At 50 meters the 22 dents where as the 177 keeps going through.
Food for Thought: With the higher velocity spring rifles here in America I have hunted game at distances of 60 to 70 yards. I was successful of harvesting a rabbit with a 20.5 grain .177 cal. at 64 yards. months later using a 21 grain .25 cal. at 62 yards the pellet bounced off a rabbit's head and he ran away. With similar weather conditions, weight of pellet and spring type in the rifles. The only difference is the diameter of the pellet. This suggests that wind resistance was the factor. Since you have set up all that equipment. You might try the Beeman with changeable barrels .177/.22 from your earlier video using same weight and style pellets and see what happens.
Good job Giles. Just proves the formula involving mass and kinetic energy or the old adage: do you want to get hit by a sports car doing 70 or a freight train doing 40.
Thank you Giles for all your hard and persistent work,you do deserve a pat on the back sir! very interesting data and honestly a little bit of an eye opener! My only small criticism is the graphs on your webpage are in poor resolution and I would enjoy printing them off as a reference (apologies for my nit picking Giles!!!) Well Done Again !!
5 foot-pounds is more than enough power for a perfectly placed shot, to make matters worse there aren't a lot of break barrels that would put enough and precise power on game at 70m. Thanks for the video it's so informative 👏👏
Thank you for taking the time out of your own personal life to do that. I think I get the message. Heavier for hunting!?! I think I agree even though a little baffled. Thank you
Great job, Giles! I had a feeling my H&N's were pushing out more energy, retaining that "smack" a .22 is supposed to. My .22 PCP is shooting at 1126 fps, with about 18 ft lbs. I'm using the H&N Snipers or the Rabbits for small game, and Air Arms 15 grain ball points for just plinking. Hey, $10 USD for 500 rounds isn't bad :D
Excellent work, I truly appreciate the data. While I am not required required to be below 12 Ft/lb it is great info that I will take into consideration with my next pellet purchase.
I just recently became interested in purchasing either a .22 or .177 rifle and I find this video very helpful in making a decision. And as you say, "Glue is expensive"
I read somewhere that it takes 4 foot pounds to pass through a rabbits scull so that is as far as you can shoot, as long as you can hit a rabbits scull at that distance. I enjoy your show thanks.
Even out at 60m a pellet from a full power sub 12 ft lb airgun has enough energy to kill a rabbit but being able to shoot 1p size groups at that distance is another matter.
Super presentation Just what I was struggling with . 18m spot on scope 38m spot on again .22 / 5.5 muzzle velocity fps 921.MTC SCB Viper 4 16 50. Decided to return to 177 4.5 can't hit a thing in 22 5.5 . FX Bobcat .Regulated .
Amen to this video , mate !!!! such a great , scientific video... I'm as they say , a "numbers guy" , and i absolutely found out that a .177 would be better for my use... thanks , keep it up !
Hello Giles. Joe from Nova Scotia Canada. I enjoy your videos very much. I do however have a minor criticism. I have noticed when you shoot through the Chronograph up close. You shoot through at a downward angle over the sensor,s. Doing so, increases the distance between the sensor,s and thus decreases the resulting readings. I have experimented with this, using the approximate angle you use, and exactly parallel over the sensor,s and showed as much as 30 feet per second difference.
Yes, I love living in America, I've got many different weapons . Growing up I hunted with everything from .22 or to 30.06. My favorite for deer was a .243. It was a Carl Gustavo mark 4 and I could cut wires at 100 yards with it. Unfortunately I was young and stupid now my uncle has it! I'm hoping to get it back some day. But since he's had it for 30 years I'm not 100% sure I will get her back. I have killed deer with .22 LR at 100 yards, the .22 LR is considered deadly at 400 yards. The military used to use a 1/2 inch plywood board to decide if something would kill. IF it penetrates full thickness it is considered a deadly weapon. ( now days the computers take the ft lb at various ranges to decide BUT rule of thumb if it penetrates 1/2 inch board its deadly. .22 have been tested out to 800 yards and the CCI stingers will penetrate the 1/2 in plywood at those distances! HITTING THE target is ANOTHER CHALLENGE!!!!!!!! Now that being said I decided for the SHTF scenario to have a .22 cal nitro piston air rifle. The .22 nitrogen filled airguns using heavy round domed pellets will give you 31'ft lb at 1050!fps. You can find faster airguns but at anything above 1100 GPS you will run into variables due to breaking the sound barrier. Projectile drift to tumbling . The extra speed isn't much of a help. The reason I decided on an Air rifle for the SHTF scenario is the fact that you can buy and store thousands and thousands of rounds cheaper and takes up less space than does bullets . I love his shield, I had thought about testing the velocity drops like he did and I would have NEVER thought about the shield idea, brilliant! Now for home security I have a 500 mossberg 12 gauge with the extended tube and it will hold 10' 3in mag. 00 buckshot. 11 if you keep one in the pipe..
Nice work there Giles. I’m subscribed to a couple of other Air rifle channels but mostly around vermin control (Tony on PPPC & Jonny on ARPC) and I decided I was not subscribing to any others as they are much the same with other just ‘shut up and shoot’ which to my thinking is missing the point and pointless. I’ve watched a few of your vids now and I like what I see and hear. So Ive decided to subscribe. Yes you get various company support but you also seem to give your honest opinion and not let £££ sway your opinion..??. Keep up the good work...👍
Yes i have to agree you have tested real world data surprised me but you said it and did it straight and that’s what counts there is probably unlimited variables shape weight conditions brands and etc but it’s as real as it gets well done for the hard work Giles I tip my hat.
Well done. A good way to look at this is at 50mtrs a 177 is travelling the same speed as a 22 is travelling at 10mtrs. Thats why hunters and target shooters use the 177. 👍also the 22 has a difference of 39fps at 50mtrs between the 2 pellet weights while the 177 has only 26fps difference. Its only negligible in reality but a difference none the less.
Great video! Interesting results. Kinetic Energy = 1/2 m * v^2 so it is reasonable to expect that speed is more important. However a lighter pellet has less momentum and is more susceptible to aerodynamic drag than a heavier pellet so will lose energy quicker. Therefore for longer distances where the drag has time to significantly slow the lighter pellet, it can be reasonably expected to fare less well than a heavier one in terms of terminal energy. Have you tried modelling this with the Hawke Chairgun application or a similar ballistics calculator? I expect it would confirm your measurements and observations. And yes, I'm a physicist. All the best, Rob in Switzerland
Hi Mate, you have some fantastic Air Guns in the UK, we in Australia cannot get silencers. I have a Beeman Air Rifle which has .22 or .177 barrels. I have chosen to use the .177 which on paper is 1100 FPS. I have found that using H & N Barracuda Power @ 10.65 gr loving the results, thanks for the video and stats fantastic
This video has no loud heavy-metal guitar, no mirrored shooting glasses,no expensive logo jackets, no young ladies dressed in clothes that would leave them shivering in actual outdoors conditions, no screaming and cursing, just carefully-done testing that is verifiable and fairly repeatable. Thank you, Giles, for being one of the rare adults to make an airgun video for grown-ups!
It does have some smelly clothes though...
I don't know though, it could of been more thorough.
I have a 177 rifle set to 25 yds shoots 800 fps pellets now I know I can hunt with it.
Brilliant vid. Lots of detail and hard work put in. Clearly showing the heavier pellets carries their momentum from their extra weight better.
.177 is faster and has a flatter trajectory and here in the USA there's no FAC requirement for airguns of any type.😁 My .177 Diana 34 puts out close to 15ft lbs with average weight pellet and close to 17 ft lbs with a slower but heavier one like the 10.5 Crossman. I'll take faster and flatter any day esp when dinging nuisance chipmunks, those things sit still like a 5 year old with ADHD and run like Usain Bolt...
This confirmed what I always had in mind about the behaviour of heavier and lighter pellets relative to distances. Thank you.
I had to watch this twice and rewind a couple of times but it was worth it, Well done and a great video. It's people like you buddy who take the time and effort to make these vids to educate all of us out here. Keep up the good work my friend and keep them coming.
Most or at least many of us wonder about research and test result but do nothing about them except hope "someone" would do it and explain the why and how of it all. Kudos to you for your perseverance and obvious love of the sport. Keep up the good work.
Outstanding! This is what I have always wanted to test since I tried to work out what caliber to choose for my first 12 fpe air rifle when I was 16 in 1979. I chose a Feinwerkbau Sport .177 on the basis of a magazine review by an American hunter of African Big Game, used to handling .577 Nitro & .458 WM who was shooting rats with one, on his riverside mooring. I still have the old Feinwerkbau, but I'd knackered it in 10 years of heavy use. I'd rather buy a new HW97 .22 than get the FWB restored now. You are inspiring me to get back into airguns after years of full FAC firearms. Congrats on being one of the most watchable & charismatic shooting pundits this side of the legendary US YT great, Hickok45! I am now a new subscriber.
"Glue is expensive" LOL!!!! Great video and information that has helped me decide on a .177 vs a .22 rifle.
Hey Giles, I am a scientist and I thought your experiment was sound and has yielded some great findings. It backs up what I thought, explains why AA Field 16 grain are similar in trajectory to the lighter and faster Daystate Li 14.3 grain. Excellent job mate. Jonny
why not match a ten grain.177 pellet to a 10 grain ,22 pellet then see what calibre performs best using to identical make rifles in both calibres at the sub twelve foot pounds British limit, that would be interesting to see !
Physics predicts that a .177 should do better. Higher sectional density suggests better energy retention downrange.
kempouk More in favor of .177. Sectional density is mass/"caliber area". More mass per less area is even better than "the same mass"/"less area".

I literally just finished watching that video..
Cubleycat!
cubleycat....what happened with your channel. you did some downright outstanding shooting. Dave
Very interesting Giles. Thanks for your hard work on this. Steve
They Steve good to see you here with the UK lads buddy
+Mark (Mark HW97K) Thank you Mark... been a Giles fan for years. Steve
+Airgun Exploration & Advancement Channel looking forward too many more of your videos Steve 👍🏻👍🏻🇬🇧🇺🇸👏🏻
You are awesome, Giles. We are not worthy, We are not worthy. You have put quite a bit of work in to that one.
I finally found the video that I was looking for in determining the pellet speed differences between .177 and .22 at various downrange distances. Your results were contrary to my speculation... but seeing the chronograph results I have to go along with your data. I am thankful that you actually set the chronograph at the various distances to measure the pellet speed at the various distances and not calculate the pellet speed based on the ballistic coefficients and the distances of the pellets. Looks like you've put a lot of thought and time in making this video. I learned something new today. Thanks.
Now that is dedication. Thank you!
Great video Giles. Thanks for taking the time to get all the data and prep the video for us. I have found that your findings match mine in real life vermin control. I was finding that jacks and crows were some times not fatally shot when using JSB Exact at just shy of 50 mtrs. Respect for quarry got me to move to the JSB Exact Heavy and this has been much better. This is .177 sub 12 fpe btw.
get some ballistic gel blocks and put them down range, measure penetration/damage? :)
+usingthatlogic Great idea this simulates flesh not bone. Not saying it should not be done mind
+or some rabbit skulls from local butchers?
course then need to disect em, so maybe need to be a vet too lmao
Was just thinking the same thing but you beat me to it lol
This will solve everything
The most informative pellet video I've ever seen. Thanks Giles for taking the time effort and expense to produce it 😉
great job on the charts, i have some charts and talks about the subject scattered some where on my youtube channel, the .177 is a ping pong ball in ballistic coefficient, high speed and energy short lived while heavy pellets are like baseballs retaining lots of wallopy down range, in general heavy objects retain more energy then light objects, i have done the 25 yard chrony test on hundreds of pellets, you can cheat a little with knowing the ballistic coefficient of pellets done at 25 yards and then use a little math to finish it out to 100 yards, a light wad cuter in .177 would be for a example 7.0 gr .010 b.c. value and a jsb 10.34 grain .030, just looking at the numbers you see that the jsb is 66% more efficient at velocity retention and it means at long distances the wad cuter will slow down quickly and have hardly any energy to spare, many occasions a heavy round nose will even reach the target first at longer ranges, the high velocity marketing in america has fooled some to think alloy pellets are fast, this is true but only to 25 yards, after that they have a dramatic loss in energy and velocity, so for longer ranges heavy pellets are faster, think of the rabbit and the turtle story, the slow turtle catches up while the rabbit sleeps, light pellets sleep and heavy pellets carry on, its just the opposite of what we think, light pellets are for close range 0-25 yards, medium pellets are for medium range 25-40 yards and long range are the heavies 40-100+ yards if possible, many people associate lighter weight with a fast trip but they forget air resistance that a lighter pellet just cant handle of the shape like a flat nose, pointed are ok but round is just a little quicker, thats why our jets went from pointed nose to more of a round nose, many like to keep pointed pellets around 30 yards and at 800 fps and under since it can be a bit picky, this is why the 25 cal springers do so well with pointed pellets due to a drop in velocity just right for a pointed pellet, where as round nose pellets that are long and heavy seem to not fuss at higher speeds and loves all distances
Being brand new to air rifles and the safety involved in safely enjoying my new hobby I came across your video's and channel. You sir are very good at teaching a novice. I have learnt so much from your informative videos. I also like your delivery. Of course, I subbed you. Once again, thank you for all your hard work and dedication to this matter, I am very grateful and you've made me a smart and safe user of an air gun.
Nice one giles. Your findings apply to all projectiles. The heavier slower moving projectile will lose less energy than the smaller faster moving ones. I'm a keen airgunner but I also have rim and centre fire rifles as well. Recently I was given a lesson in balistics by my local balistic "Yoda" who explained to me when I was considering trying a 40 grain bullet as opposed to my usuual 55 grain one why the 40 grain bullet, although intialy travelling much faster would, as the range increased, drop off and loose energy much faster than the 55 grain bullet. Thanks for taking the time and putting in the effort to prove it.
Thanks Big Fella, as always an entertaining and informative video presented in an easily digestible format. There are a lot of people that could have put the same science out there as a cure for insomnia!
Keep doing what it is you do so well and good luck!
Great info and I like the dry wit thrown in for entertainment. I've often thought of doing this, but didn't want to risk my chrony. Coming from a lifetime of firearms shooting, this just confirmed what I know to be true. Heavier projectiles of the same caliber retain velocity and energy better than lighter ones do at the same distances. Heavier projectiles also have a more pronounced curve to their trajectory, so the trick is to find the tradeoff between flat trajectory and retained energy that works for your needs. Flatter shooting pellets give you more leeway in regard to aiming as well. There is a thing called Point Blank Range. This is the distance range where you can hold dead center of your target and not have to worry about hold over/under. My .177 cal. Beeman R9 for example, throws Crosman Premier Heavy pellets weighing 10.58 grains downrange starting at 747 fps. Zeroed at 15 yards and shooting at a 1 inch target, this gives me a Minimum Point Blank Range of 11 yards and a Maximum Point Blank Range of 38 yards. Anywhere within those distances, I can hold dead on the target and know I'll hit within that 1 inch target. The trajectory starts out a couple inches low at the muzzle due to the distance between the center of the bore and the center of the scope, climbs to a half inch low at 10 yds, continues to zero at 15 yds., then continues to rise to a half inch high at 25 yards, then starts falling back through zero at about 34 yds and back to a half inch low at 38 yards. That doesn't take windage into account, so there's always that variable, and even vertical impact can be affected by the wind. Those numbers are what I can do on a calm day, so I generally try to stay a couple yards shorter than the maximum to be safe. This 15 yard zero gives me the most useful range for my needs. With lighter 7.97 grain Crosman Premiers a 15 yard zero yields too high a trajectory path at midrange of nearly an inch high. I have to move my zero out to 20 yds to stay within a half inch of point of aim, and the min and max distances shift farther away by a couple of yards.
my hw110 is at 10.7ftlbs @ the muzzle....... i recently took a long ish range rabbit with a headshot in the field.
i marked my point, and the rabbits point and ran to get my measuring tape.
using 16g .22 i had this kill at 58m.
i was comfy with the shot as id practiced my ranges and hold over/under. but i dont think id attempt any further.
i remember as a kid having a pistol that shot at 4ftlbs, and i used it for point blank shots when dispatching mixy rabbits.
so, your experiment with having 4-5 ftlbs down range at 50 meters seems about right with my experience.
im glad someone has done the experiment to prove my theory haha! thanks again.
This is the best demonstration on pellets I have seen ever. Thank you man. I have decided to try piledriver .177 at 21 grain with my RWS 350. I hope the combination of high power and heavy pellets along with some bullet lube should help my range dramatically
not sure where ur getting 21gr from lol the current heaviest .177 is just shy of 17gr lmao you shooting a mod?
Wow this video is 3yrs old & underrated. You’re an impressive & professional presenter keeping things very interesting, humorous, clear, concise, informative, & unbiased. Excellent work investing in the equipment, filming, compiling the data, delivering the info, & thoughtfully wearing the same dirtied outfit.
I’m more interested in long range shooting myself & subjectively, I feel like .177 is easier to hit a target at long range when I use a lightweight alloy pellet, the Gamo Raptor, compared to when I use the same exact gun (Beeman RS2) chambered in .22 using RSW Superdomes but maybe they are both traveling the distance but I need to compensate more for the drop from the .22 & because my scope was adjusted for the .177?
If you’re still making videos, would love to see a video comparison of exactly how far (distance) pellets of each caliber (same make/model) can travel before dropping & also another test to see the difference in muzzle velocity & velocity down range if an equally heavy .177 pellet & a wider .22 weighing the same w/ similar shape were fired.
Full marks for your work Giles
Wonderful and beneficial project! I don’t think people really appreciate the work, time and effort an analysis like this took! Plz ignore any negative comments from those that can’t or wouldn’t do as such. I’m now subscribed!
Well done Giles. A bit of info I've wondered at for some time but don't have the equipment, time, patience to figure out. Thanks for your hard work to give us the answers, haven't seen this done as yet, again well done. Cheers!
Great job, thanks for putting all of the work into this video. I have been told numerous times that I was shooting too heavy of a pellet in my videos and I should shoot this brand and weight or that brand and weight. I know how my rifles shoot, and I've always felt that I was delivering plenty of energy and accuracy with my choices. When you connect on a breast shot on a dove from 153 yards and it sounds like it was hit with a baseball bat, you know what pellet your rifle prefers. Thank you again sir (you have helped me prove my point to the trolls)
Been waiting for someone to do this for ages, very interesting cheers mate
You lazy bastard 😂
Thank you for this great video! I got my Hatsan yesterday, and today my family( wife and two little girls) had great day shooting on targets. Greetings to you, especially to your wife :-)! Thank you man!
Fantastic testing and comparison of thos calibers - but....interesting would be how acts a .177 pellet with the same weight as a .22 caliber pellet!?!?!!
For example a .177 JSB Exact "Monster" with 13.43 grain or a "Beast" with even 16,2 grain!!!
great video thanks for the information . that had to take time I have been testing my Diana 48 in 177at 10 feet shooting a10.65 gr Baracuda power 803 average fps 14.91 FPE have a whole box different brands an weights of pellets to test welded up a pellet trap have 10 yards in basement this summer move outside I love springers, I believe I have watched all your springer videos well this old man saying good night an GOD bless from the USA
good testing, appreciate the effort! your data is fine for the UK and lower places near a large body of water. you're basically near sea level with a high humidity. thick air made thicker with humidity. i know you've been out to Arizona a couple years ago, get a kilometer or so above sea level, and 5-10% humidity, thinner air with less dense air due to water vapor.
i'm just 20 miles SW of chicago, 245M above sea level and far enough from the lake that it's usually not that humid. 4-5 months of the year (fall-winter) the humidity in my condo falls below 20% (forced air heating, gas powered).
then there are all sorts of pellet designs, flat heads, pointed, domed, hollow points, hollow points with points in the hollow, etc. but i think you've laid a good baseline for general performance.
a pleasure watching. no cheap comicbook fantasy leaders, no crappy overblown music. just good clear facts. enjoyable. and... i learned something toboot! Thanks. nice job.
Very thorough.
Also i liked the added humour made it watchable😂😂😂
Great video, when i was younger and shot a lot at a club, we used Ballistic gel at 50 yards (sorry feet and inches guy) noted the depth of the pellet and then placed blocks of gel at 60 yards and 70 yards and it depended a lot on the weight of the pellet
great shooting and lots of work but I say this 22 or 177 in the head its dead and my self have used nothing but 177 for 50 years and it kills very well and unless I can shoot in the head no shot move on to another head shot great video Giles and lots of hard work well done
Well Giles, your like the busses round here. You wait ages for one and 5 turn up at once. All the very best and glad your back on form.
Years down the road Giles still scores with this interesting and informative video. Many thanks. I always enjoy your vids; a little humor and a good info!
Interesting, very very interesting indeed. 12 minutes of education, well done young man, and entertaining to boot.
Great work....what if we stand up and shoot an object near ground with a .22 tx200 @ 20-50 meters....is there a significant change in trajectory on .22 vs .177? Thank you
thanks for this video Giles as a new air gunner I found this very interesting and keep up the good work I really appreciate the videos and I'm glad you've carried on after the Christmas competition incident thankyou Giles
This is incredible information. Thanks so much for taking the time and effort! Love your stuff
Wow, this is incredibly interesting! I had already hypothesized that lighter pellets would slow down faster, but seeing it actually come true is amazing.
well all i can say to that is if you want to give a rabbit a headache before tea then use a .22 pellet otherwise stick to .177 for the kill :) it's a no brainer lol
Correct me if I'm wrong but my takeaway from this is .22 and .177 are more alike from a practical hunting standpoint. Their is greater difference between light and heavy pellets in the same caliber than between the calibers themselves. As for hunting my - limited - research came up with a working minimum of 12 foot pounds. Lesser foot pounds calls for much more precise aim. So with 12 fps you have to hit a quarter sized target. With around 10 fps you have to hit a dime sized target (US currency). Basically the dime is around half the diameter of the quarter.
Good bit of work Giles we all love the technical stuff!
Thank you for doing this, the question came up and here it the video. Brilliant. Years ago I read in a Airgun Magazine from England that 8.44g is the best pellets for 177 Springers and you just proved it again. I am sure if you use a 470cm barrel as apposed to the 370cm, the 177 will even proof to be the better hunting pellet over all.
*Nice Research... FYI Slug is holding speed in distance because it has better balistic coeficient.*
Best pellet test vid, nice N easy. I generally use H&N FTT for .177 in calm conditions and JSB Heavies in breezy weather. In .22 RWS Hobby's up to 35-40 yards and then any of these AA Fields, JSB Exact and Logun Penetrators any further.
great effort has been made to bring all these data. I wanted to know the trajectory results in terms of fps and muzzle energy. i got the results. Thanks.
Great video brother I just got my first 22 Cal BB gun an I have 9 ,177 Cal thank you for your helping me understand the difference much respect from Hamilton Ontario Canada 🇨🇦✌
I could potentially add that a heavier pellet may have a bigger arc to its flight, making it slightly harder to judge these things at varying distances... Where a lighter pellet may be beneficial at long varying ranges?
Giles,good video.Thanks for the hard work.
The way things are going in the U.S.,we may only have air rifles too,but we may not have lead to shoot in them. Wayne
What a brilliant vid! And best of all, with our low powered UK kit. Thanks Giles.
Best airgun video I've seen on ballistics in quite a while. Thanks for taking the time to do it I know it's a pain in the butt. If we all had 100 yard indoor ranges everything would be great. But if you using your rifle for hunting you gotta make those dope adjustments in the field. Here in the states Gamo Loves to use their feet per second As a selling point especially with their aluminum ammo. And it just doesn't hold up. I have two Gamo air rifles Big cat 1400 in 177 Calibre and the Gamo Hunter Extreme SE in 22 caliber. Both rifles deliver on Power and accuracy with the right pellet. I am sold on h&n baracuda Hunter Extremes. The speed is much lower But the impact is impressive. I'm using jsb exact heavy Diablos in my 177 caliber Daisy 880 multi pump. At 50 yards I'm still on target. Not a lot of muzzle energy out of that rifle but for small birds or squirrels completely adequate. My HATSAN BT65 QE PCP Air rifle is not as picky. It will take an 18 grain jsb exact heavy Or a H&N 22 grain barracuda and slam it through two inches of hardwood at 50 yards.
This video does show that the BC of the JSB exact jumbo 22 caliber 15.89 grain pellet is 0.0227 . Out of a Walter LGV master pro airgun . If you enter this BC number in chairgun with the muzzle velocity of 553.5 the number he has work out at every meter . Great work on the video .
Excellent analysis, thank you. I use Zan slugs in 177 - 10gr in my sub 12, usually up to 40m for rabbit hunting and they stop the prey instantly, with a very nice thud too. The 10gr Zan slugs fly slower than the 10.34gr JSB Hades and Exact Heavies but seem to have much less drop over the distance, about 5cm less drop.
i was an evironmental scientist, and it looks ok to me. now looking at heavier pellets. cheers thanks for the science
Great video fella, can't beat getting out there and getting real physical results!! Thankyou for making the effort bro, this has helped me decide upon my next rifle, thumbs up, smiley face etc pmsl
Well done, Giles. I did not expect that. As always, your videos are both fun and educational. Thank you. Karl
P.S. The picture is of my wife, not me. :>) Oh, and please don't stop cranking them out.
Informative and entertaining as always! Well done Giles!
Great video. I've just bought my first air rifle. You could always place some ballistics gel at a distance and measure the penetration/damage
Good science.
I would prefer it, if you added two extra columns to convert ft/s to m/s. And maybe two more to give ratios of current_speed/maximum_speed. Same for converting kinetic energy to joules.
It is irrelevant if you smell, we can't feel it.
As a nuclear physicist and a military ballistics engineer, I can definitely say you have it all wrong however I totally enjoyed the video presentation just the same. Tis' a damned shame I have to search across the pond to get these kinds of stats since nobody here in the states can seem to take the time/effort to do this kind of work for those of us who enjoy a wonderful day out shooting our air rifles, pistols, revolvers and the like. Thank you mate for a great video.
Bo Hector all wrong in what way?
@James: you beat me to it; hat tip. One would think if Bo was going to write so many pointless words after telling someone he was "all wrong" he could have at least included a reason or two.
@James I know this is an old video but I've just stumbled across it and thanks for all the work. Very good information. I hope Bo Hector was just kidding because your methods and findings look real good to me, an engineer.
Here in The States I'm just starting to experiment at grouping .25 cal at 100 yards. So far I've had the best results with 25gr pellets only because at those ranges I'm running out of dots in my scope.
Really enjoy your video and find them very informative.
Thanks
Great video! Very informative. I use a .177 cal. pellet at 10.5 grains and am quite pleased with the result. Thank you for your hard work.
Nicely done. :) Results are completely expected. Air resistance increases to the square of speed increase, therefore, placing the gun's energy in speed rather than in the mass, causes a larger loss of energy over distance. Energy = Mass X Velocity X Velocity (E=MV²)
Excellent information saved me hours of work, But came to the conclusion a while ago now that a heavy 177, e.g. bisley magnum 10.2 gr will hit harder, fly flatter, than a light weight 22 by just looking at the 6mm exterior ply backing the target. At 50 meters the 22 dents where as the 177 keeps going through.
Confirmed what I always believed about .177 pellets and energy retention. Great job
This is one of your better videos. It really is surprising. And I can smell you all the way here in South Texas, go wash them knickers:-)
Food for Thought: With the higher velocity spring rifles here in America I have hunted game at distances of 60 to 70 yards. I was successful of harvesting a rabbit with a 20.5 grain .177 cal. at 64 yards. months later using a 21 grain .25 cal. at 62 yards the pellet bounced off a rabbit's head and he ran away. With similar weather conditions, weight of pellet and spring type in the rifles. The only difference is the diameter of the pellet. This suggests that wind resistance was the factor. Since you have set up all that equipment. You might try the Beeman with changeable barrels .177/.22 from your earlier video using same weight and style pellets and see what happens.
Good job Giles. Just proves the formula involving mass and kinetic energy or the old adage: do you want to get hit by a sports car doing 70 or a freight train doing 40.
NEITHER!
Thank you Giles for all your hard and persistent work,you do deserve a pat on the back sir! very interesting data and honestly a little bit of an eye opener! My only small criticism is the graphs on your webpage are in poor resolution and I would enjoy printing them off as a reference (apologies for my nit picking Giles!!!) Well Done Again !!
5 foot-pounds is more than enough power for a perfectly placed shot, to make matters worse there aren't a lot of break barrels that would put enough and precise power on game at 70m. Thanks for the video it's so informative 👏👏
Thank you for taking the time out of your own personal life to do that. I think I get the message. Heavier for hunting!?! I think I agree even though a little baffled. Thank you
Thanks for all your time and work on bringing us this great info!!!
Nice graph numbers comparisons. I truly appreciate your work efforts and eye opening results.....
Great job, Giles! I had a feeling my H&N's were pushing out more energy, retaining that "smack" a .22 is supposed to. My .22 PCP is shooting at 1126 fps, with about 18 ft lbs. I'm using the H&N Snipers or the Rabbits for small game, and Air Arms 15 grain ball points for just plinking. Hey, $10 USD for 500 rounds isn't bad :D
Excellent work, I truly appreciate the data. While I am not required required to be below 12 Ft/lb it is great info that I will take into consideration with my next pellet purchase.
Giles you are the top man! Thanks for doing what you do with airguns.
Fascinating stuff, Giles. Thanks. I like JSB Exact heavies in my .177. Would be interesting to see how they retain energy at distance.
I just recently became interested in purchasing either a .22 or .177 rifle and I find this video very helpful in making a decision. And as you say, "Glue is expensive"
What did you go for?
I read somewhere that it takes 4 foot pounds to pass through a rabbits scull so that is as far as you can shoot, as long as you can hit a rabbits scull at that distance. I enjoy your show thanks.
Even out at 60m a pellet from a full power sub 12 ft lb airgun has enough energy to kill a rabbit but being able to shoot 1p size groups at that distance is another matter.
I appreciate all the work a question we have had in our minds great content keep it up
Super presentation Just what I was struggling with . 18m spot on scope 38m spot on again .22 / 5.5 muzzle velocity fps 921.MTC SCB Viper 4 16 50. Decided to return to 177 4.5 can't hit a thing in 22 5.5 . FX Bobcat .Regulated .
Amen to this video , mate !!!! such a great , scientific video... I'm as they say , a "numbers guy" , and i absolutely found out that a .177 would be better for my use... thanks , keep it up !
Lovely bit of physics. Good work mate!
Hello Giles. Joe from Nova Scotia Canada. I enjoy your videos very much. I do however have a minor criticism. I have noticed when you shoot through the Chronograph up close. You shoot through at a downward angle over the sensor,s. Doing so, increases the distance between the sensor,s and thus decreases the resulting readings. I have experimented with this, using the approximate angle you use, and exactly parallel over the sensor,s and showed as much as 30 feet per second difference.
Yes, I love living in America, I've got many different weapons . Growing up I hunted with everything from .22 or to 30.06. My favorite for deer was a .243. It was a Carl Gustavo mark 4 and I could cut wires at 100 yards with it. Unfortunately I was young and stupid now my uncle has it! I'm hoping to get it back some day. But since he's had it for 30 years I'm not 100% sure I will get her back. I have killed deer with .22 LR at 100 yards, the .22 LR is considered deadly at 400 yards. The military used to use a 1/2 inch plywood board to decide if something would kill. IF it penetrates full thickness it is considered a deadly weapon. ( now days the computers take the ft lb at various ranges to decide BUT rule of thumb if it penetrates 1/2 inch board its deadly. .22 have been tested out to 800 yards and the CCI stingers will penetrate the 1/2 in plywood at those distances! HITTING THE target is ANOTHER CHALLENGE!!!!!!!! Now that being said I decided for the SHTF scenario to have a .22 cal nitro piston air rifle. The .22 nitrogen filled airguns using heavy round domed pellets will give you 31'ft lb at 1050!fps. You can find faster airguns but at anything above 1100 GPS you will run into variables due to breaking the sound barrier. Projectile drift to tumbling . The extra speed isn't much of a help. The reason I decided on an Air rifle for the SHTF scenario is the fact that you can buy and store thousands and thousands of rounds cheaper and takes up less space than does bullets . I love his shield, I had thought about testing the velocity drops like he did and I would have NEVER thought about the shield idea, brilliant! Now for home security I have a 500 mossberg 12 gauge with the extended tube and it will hold 10' 3in mag. 00 buckshot. 11 if you keep one in the pipe..
Nice work there Giles. I’m subscribed to a couple of other Air rifle channels but mostly around vermin control (Tony on PPPC & Jonny on ARPC) and I decided I was not subscribing to any others as they are much the same with other just ‘shut up and shoot’ which to my thinking is missing the point and pointless. I’ve watched a few of your vids now and I like what I see and hear. So Ive decided to subscribe. Yes you get various company support but you also seem to give your honest opinion and not let £££ sway your opinion..??. Keep up the good work...👍
Great video Giles, Love videos like this, where you can actually learn something!
Excellent work as usual Mr B
Very nice. Thank you Mr. Barry. And thank you Mrs. Barry for your patience.
great video, its all about ballistic coefficient, nice way to show it in a graph. This video will help a lot on picking a pellet and its weight
Great video, bud. Appreciate all of the hard work put into it.
Yes i have to agree you have tested real world data surprised me but you said it and did it straight and that’s what counts there is probably unlimited variables shape weight conditions brands and etc but it’s as real as it gets well done for the hard work Giles I tip my hat.
Well done. A good way to look at this is at 50mtrs a 177 is travelling the same speed as a 22 is travelling at 10mtrs. Thats why hunters and target shooters use the 177. 👍also the 22 has a difference of 39fps at 50mtrs between the 2 pellet weights while the 177 has only 26fps difference. Its only negligible in reality but a difference none the less.
Great video! Interesting results. Kinetic Energy = 1/2 m * v^2 so it is reasonable to expect that speed is more important. However a lighter pellet has less momentum and is more susceptible to aerodynamic drag than a heavier pellet so will lose energy quicker. Therefore for longer distances where the drag has time to significantly slow the lighter pellet, it can be reasonably expected to fare less well than a heavier one in terms of terminal energy. Have you tried modelling this with the Hawke Chairgun application or a similar ballistics calculator? I expect it would confirm your measurements and observations. And yes, I'm a physicist. All the best, Rob in Switzerland
Cracking video again Giles, very informative. Keep up the excellent work.. And thank you.
Hi Mate, you have some fantastic Air Guns in the UK, we in Australia cannot get silencers. I have a Beeman Air Rifle which has .22 or .177 barrels. I have chosen to use the .177 which on paper is 1100 FPS. I have found that using H & N Barracuda Power @ 10.65 gr loving the results, thanks for the video and stats fantastic
awesome vid 'its about time someone showed the fps at distance 'your really kewl'keep up the good work.
