@@bowmanoutdoorsHi good day dear bro, do you question? You think Fx Panthera .177 cal 20 gr slug Will a 700mm beat a 600mm in the accuracy department?
@kricketkricket6737 I would love to get my hands on the Panthera and wanted to buy one, but I’ve already got so much invested. Judging the reviews and information I find, I think you’ll be happy with either! Slugs do better with the added stability of velocity and spin. Those two variables should perform slightly better with the 700mm barrel. With the slug in the barrel longer, a bit more of it will depend on your skill and flex in the barrel. You should get higer velocity from the 700 though. The 600mm is a bit more portable and with less length, theoretically marginally stiffer (less flex). I’d pick the 600 personally as it will get a moderator and added length and flex with that. For me, 600 is plenty unless you are going out to extreme ranges of 150yds+. If that’s the case, I’d go 700 for the added range. Hope this helps and great question. Thanks for your support and comments!
@@bowmanoutdoors Thank you for your help, you have a nice, high-quality channel. I do groupman and hunting with minimum 55 yard, maximum 110 yard accuracy. For example: If I buy 600 mm and 55 yards with 1.5 sm accuracy, 70 sm and 1 sm accuracy, otherwise the same?
@kricketkricket6737 thank you for the compliment. I am not sure I understand your question fully but for 55yds to 120yds, you will have no problem with the 600mm barrel. It would be my preference, but it is a personal choice. Pellets are a bit less expensive and less grains to choose from but should be single hole at 55 yards shooting sub 950 fps. For slugs, find the one your barrel/gun like and tune for that specific weight and you are golden!
Great video guys! Just sub'd! So I ran a similar test with the .35 cal over on UpNorth Airgunner, but what I have found is that barrel length matters more to utilize longer barrel dwell time by runing heavier ammo at higher pressures. With other big bore airguns unregulated the valve is often held open longer with the backpressure of the slug in the barrel. Since you are running a relatively light weight projectile for that caliber it might be leaving the barrel so quickly it can't build up that barrel pressure. Try running that same test with some 45 grain to 50 grain slugs at a high reg pressure. Again - great video and I love the ending. I have a few Caldwell "4 pointers" hung in my gun room as trophies too. They taste a little game-y but make for great wall hangers! LOL!
Awesome information and thank you for the suggestions. I’ll head over to your channel and show some support your way too! I’m looking at some AVS slugs to test in heavier projectiles, then realized I’m going to have to “slug” The barrel and measure so working that out now! Who knew how fun and exploratory (expensive) this could all be, but worth it to learn and spend quality time with my son! (Who showed no mercy in making fun of my “accuracy” in putting that Slug right in the numbers!!! 😂 Thanks so much for the support!
Wow, just wow! You make such amazing, informative, videos! Impressive and a standard we strive to! You are an advocate and great advocate for this sport! 🙏🏻
Got a good laugh from chrono lol. I shot mine back in the summer with a 5.56. Afterwards I broke down and bought the new FX radar and love it. So easy to use just sit it on the table next to me.
Absolutely. The FX radar is super easy. I’m curious how the green 2 chrono will work 😀. Turns out once to shoot them, they don’t work so well. Thanks for sharing and I do feel a bit better than I’m not the only one to have done this
I see you guys haven't uploaded in 7 months, are you planning on making more videos? I enjoy the laid back, normal straight talk and your Father/Son relationship. Please don't stop now, I just subscribed lol... Thanks for all you have made so far, definitely hope to see more!!!
We were just talking about that yesterday. Yes, we plan on more videos. A bit of transition as Logan graduated and started his career but things are stabilizing and we are planning on getting back to it. Thanks you for the encouragement and support! 🤙🏼
Oh my Goodness! I laughed SO HARD when you said, "That's an interesting shape that you drew!" Great shooting Guys!!!!!!!!!😃😃😃 I literally had tears laughing so hard when you shot the chronograph!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I appreciate you sharing and am glad you enjoyed it. Having fun and enjoying this sport is a big part of the objective! Thanks for the feedback and support! 🤣😂
"Do longer barrels matter?" Yes and no. It depends what you're trying to achieve. Longer barrels will generally net you more velocity at a lower pressure- i.e. more efficiency. Typically, you CAN get the same velocities with shorter barrels, but you'll be spending more air to do it (it'll also be louder). In both cases, there's limitations. There's a point of diminishing returns with barrel length- i.e. too long, and you're doing more harm than good. With short barrels, depending on the projectile you're trying to launch and the target velocity, you may not have enough barrel to get there. It's all a balancing act.
You are correct. A balancing act indeed. The longer barrel also leaves the slug in contact longer so movement is the shooter or system plays a larger role. I found out I’m less accurate with the longer barrel when I thought accuracy would be improved. Thanks for the comment and feedback
What about a FX with either a 700 or a 800 MM barrel at 950 fps where would the power wheel be set for the best results with the listed tune? Among other things affecting accuracy what is your gun of choice ?
Great video, but I would mount the chrono on the scope, hanging on barrel effects the harmonics so precision will be less. Then you can tune & test at the same time 🙂
Thank you two. I've been wondering what that 800mm .25 barrel does for a while now. I'm wondering if you'll get a bigger increase with a higher reg pressure and more hammer?
We do have the tungsten hammers installed. We could run that test if it would be helpful for you. We have them turned down as it was the best area for accuracy and to stay clear on the transonic zone. Now I’m curious of the results of your question… I know what I’ll be experimenting with next 😂
@bowmanoutdoors I'd love to see it. I currently have the 1st stage reg delete in mine, with the reg set at 160 bar shooting a 50 grain at 995 fps with 3.7 on the hammer. It's a laser.
@bowmanoutdoors I love it. People don't realize, but I get a maximum spread of 14 fps with 45 shots. I use the 700cc tank, though. A lot of people assume you get a crazy extreme spread, but you don't. The 1st stage reg holds the gun back if you want more power and a faster plenum refresh. It's a lazer, too. I use AVS .253 44, and 50 grain boattails.
@dougiefresh3767 that’s great information. Wow you shoot much heavier than we do, but this just maybe my next experiment. Looks like we are going to do lube/no lube video next, but I’ll add the reg delete to the list. I’m now curious! 😀
The first shot is a common theme with FX impact users and that is the first one is always low and slow. Even when you think you have a fantastic tune which you do but it can be fixed to where you don't have that low and slow first shot
Closed down the valve adjustment and left everything else the same and shot lights out during our Hurricane Helene power outage 😀. Took it a bit shy of the third line and didn’t have the “low and slow” issue. Could be coincidence but both of us shot our best groups to date consistently across 2 evenings.
Since you guys both have that rail under the bottle, it might be worth getting a mount to put your chronograph there instead of on the barrel. Then you could check accuracy at the same time since it won’t mess with barrel harmonics from it hanging there. Nice rifles, I think they’re both setup well. Makes me want to pick up an M3 and sell my old one.
Thanks for the compliments and support. You are correct. I’m actually thinking about upgrading chronographs to one that would not be mounted and would be for all our firearms. If we don’t upgrade, a mount is definitely needed. Thanks for the support and feedback.
I thing you've messed the implantation of the second barrel 800, since you've should tighten the back screw first to be sure you're in line with slug port then go to other task.
Presuming the valve adjuster was set properly for the 700mm, with all other settings being the same, it needs to be opened a bit more to maximize the 800mm.
I agree but we didn’t want to skew results or introduce variables if we could prevent it. We may test again at higher pressure or perform additional testing to determine additional performance criteria. Thanks for the information and comment
I purchased an fx panthera 600 mm 22 caliber. I wanted a 700 mm but it was just too long. My question is if you switch over to 25 caliber slug liner with a 600 mm barrel can will this combination put out as much or more energy and accuracy as shooting 700 mm with a 22 cal 40 grain slug?
Congrats on the new Panthera. (Slightly jealous but spent all my hobby money on a compound bow setup) 😂 Great questions. The answer to both is yes…. But it isn’t that simple. Energy is a calculation of weight and velocity so if using the same grain slug in either .22 or .25, increase in velocity will increase energy downrange. Generally, more mass would be carried with larger caliber but doesn’t have to be. Test various slugs and see which is best for your application. As for accuracy, I suggest starting with testing slugs, getting the best groups then dialing in the tune to the specific slug. We shot very tight groups with both calibers and the tuning is enjoyable process.
@bowmanoutdoors OK. Appreciate it. Thanks for getting back to me. Caliber, barrel lengths and slug weight is probably the most complicated thing to understand when it comes to airguns.
There are so many variables for sure. Use the .22 with the barrel you have and test various slug weights and designs. We really love the NSA slugs and they come in many many weights, some flat base some cupped base. My gun shoots a cup base (few grains heavier also) slug better while Logan goes with a slightly lighter slug for the best results. The gun should be plenty accurate, just takes lots of testing and tinkering to find the best combination. (Precision firearms are similar with powder, BC, neck tension etc). It can be a simple or complex as you want to make it. I typically lean towards the complexity but it certainly isn’t a requirement! Thanks for your feedback and support.
Thanks! It has about the same feel but slightly thinner and the ST grip is slightly more narrow at the bottom. With the added adjustable thumb rest that is included, it is much more comfortable.
I am a huge fan of the NSA slugs. I’d get several weights from about 20gn to 38 gn and see what works best for you. You can tune your gun to the one that works best by adjusting the regulators, or valve spring knob. Each will basically adjust the velocity of the slug then find where the barrel harmonics works best. (Most consistent shot groups and smallest group size) H and N heavy slugs have also worked very well for us right out of the tin. No luck here with the FX Hybrid slugs Great question and thanks for your feedback and support.
On my particular gun it was 42 clicks (4.2 mils) at 35 yards but with the large/heavy moderator. I typically run a bit smaller/lighter moderator for that (and accuracy) reasons. Good point we should have covered. Thank you!
20 bar difference is just recommended from somewhere!?!? If we go too different the pressures take too long to stabilize but that might be in my head. I’ll do some tests and find out!
@@bowmanoutdoors A 40-50 bar difference refills the plenum faster than a 20-30 bar difference. FX says a 30 bar difference is more precise (lower Standard deviation) I go more towards 50 bc the ob of the 1st reg to take a little pressure off the 2nd reg. So 300 bar from my bottle, I let my 1st reg take roughly 100 bar off (I have it set to 210) and 2nd reg to 160 which it handle just fine. I may get a Huma reg bc it has a brass piston and can handle up to 200 bar.
Wow, you run much higher pressures than we are currently. We have the Huma-Air high pressure Reg installed but haven’t run either that high. Did your shot count drop drastically? Good thing about FX is I can adjust to closer to your pressures and if it doesn’t work, back them back where I am at. Still have to keep it backyard friendly so I don’t hack off all the neighbors again. (Tannerite, funny story 😂)
@@bowmanoutdoors I stsrted w the 600mm barrel and the 480cc bottle but I wanted more power (bc I prefer heavy slugs for the higher bc) so I upgraded to the 700mm barrel (bc the 800mm wasnt out for .25 cal yet) and the 700cc bottle. Yes, the shot count still sucks but OK bc it is a 300bar bottle.
It can and will be much better. We need to re-tune our setup and test various slugs with the new barrel length. It’s a process, and each time we make a major change to the system, we end up re-tuning and going through the whole process again. Thank you for your question and support!
Smart kid, Velocity is speed with direction. You should refer to the speed of the pallet as speed, not a velocity. Btw, most of the settings that the dad read out were pointless. The big wheel setting means nothing, as the micro wheel setting covers the whole range of hammer spring tension, so only the reading from the micro wheel makes any difference. Also, the front reg reading doesn't mean anything either when it comes to pellet speed, the only thing it controls is how quickly the second regulator fills up!
Thank you for your feedback and comments. BTW, most of what I say generally is pointless 😂. You are also correct about both the 1st reg only being there to fill the power plenum and about the micro-wheel. Thanks again for your support and feedback. 👍🏻
Thanks for sticking with us. The next one won’t be so delayed. Life, school, work, etc caught up with us but it’s all getting back in balance. Stay tuned and thanks for the support!!!!
Absolutely correct. We never shoot groups for accuracy with the chrono on the barrel. It’s amazing how much moderators, Chronograph or other seemingly minor variables have on impact accuracy! Thanks for your input
This particular model runs about $2000 but then we added accessories and optics, upgrades, etc over the last year. Great question and I’ll try to capture full build out cost.
That’s about right. Adjusting the time would result in better results but the goal was to eliminate variables to see the impact of only the barrel. It also cost me some accuracy at the range I typically shoot so I wouldn’t make the purchase next time for me personally. In this case I already made the purchase so….. 700mm is my preference 🤙🏼
Regardless what anyone says about “it’s what you do with it” size always has an impact on performance in some way. 😂 Thanks for the laugh and for your feedback and support!!!
Nothing dangerous, projectiles rise to a point, then fall along a curve. Optics are “zeroed” in our case on the fall of the projectile at a given distance. With the chrono set so close, the impact point was much lower than I had calculated, therefore hitting the chrono. Point of aim, trajectory, and point of impact all happen along an arc and I misjudged it.
Omg i stopped watching halfway the video... how can you have this spread and still want to make a video about barrel comparison. Please first get your regulators fixed and the proper ammo. For the try i give you guys thumpsupp, for the results thumpsdown !! Keep shooting anyway !!

Thanks for sticking with us. The next one won’t be so delayed. Life, school, work, etc caught up with us but it’s all getting back in balance. Stay tuned and thanks for the support!!!!
I think you should take out FX Radar from barrel accuracy will be change.
Absolutely correct. We never shoot groups for accuracy with the chrono on the barrel. It’s amazing how much moderators, Chronograph or other seemingly minor variables have on impact accuracy!
Thanks for your input
@@bowmanoutdoors I love 800mm barrel. Hopefully you keep updating about it.
E will certainly do so!
Size always matters bigger the better just one of those laws😅
Of course size matters…. 😁 thanks for the support and comment!
Long barel more groove... More velocity
And longer time under pressure in the barrel. 🤙🏼
قیمت به دولار این تفنگ بادی چقدر است
This particular model runs about $2000 but then we added accessories and optics, upgrades, etc over the last year. Great question and I’ll try to capture full build out cost.
hi guys, which caliber and how heavy are the slugs? thx
.25 caliber
38.5 NSA slugs
Great question! Thank you
I think you gain 10fps for every inch of barrel length
That’s a fair general rule but there are so many variables. There is also a length of diminishing return, but I haven’t calculated or found it yet.
I only seen a 17 fps difference or did i miss something?
700mm=980fps
800mm=997fps
That’s about right. Adjusting the time would result in better results but the goal was to eliminate variables to see the impact of only the barrel. It also cost me some accuracy at the range I typically shoot so I wouldn’t make the purchase next time for me personally. In this case I already made the purchase so….. 700mm is my preference 🤙🏼
what chrono is that?
The FX pocket chronograph. I plan on upgrading, but this one does the trick for air rifles.
Does size matter, then,do longer barrels matter😂
Regardless what anyone says about “it’s what you do with it” size always has an impact on performance in some way. 😂
Thanks for the laugh and for your feedback and support!!!
@@bowmanoutdoors 😄👍
Lmfao my Caldwell also has a hole through it 😂😂
Happens to the best of us! 😂😂
Caliber ?
.25. Sorry we failed to mention that in the video.
Thanks for your question and support.
Lube video would be interesting
Thanks for your support and we are already planning it! It won’t take a year to get the next video out. 😂
How can you shoot the crono being that close to it your dangerous
Nothing dangerous, projectiles rise to a point, then fall along a curve. Optics are “zeroed” in our case on the fall of the projectile at a given distance. With the chrono set so close, the impact point was much lower than I had calculated, therefore hitting the chrono. Point of aim, trajectory, and point of impact all happen along an arc and I misjudged it.
Omg i stopped watching halfway the video... how can you have this spread and still want to make a video about barrel comparison. Please first get your regulators fixed and the proper ammo. For the try i give you guys thumpsupp, for the results thumpsdown !! Keep shooting anyway !!
Thanks for the feedback and suggestions. We may have to try this one again once we complete our current two videos in work.
