Many years ago, one of my professor's taught me "There is no secret to consistency. It's simply doing everything exactly the same." And that has applied to so many things I've done in life. Reloading & accuracy was one of them.
It was absolutely great listening to the two of you talking back and forth. I am 81 years old and I have been reloading off and on since I was twelve and I thought I knew something about accurizing a rifle. I really learned a thing or two about that while listening to you two. Thank you.
Gordy Gritters, I thank you sir for taking your precious time to share some of your wealth of knowledge that obviously took time to amass . Merry Christmas both of you !!!
Thank you both for the information provided in an interesting way! Merry Christmas!
Thanks for the introduction. I have unrolled in one of Gordy’s upcoming classes. Great interview.
Merry Christmas to you. Thanks for the awesome videos keep them coming. :-)
Dude , Dude OMG THANKS for this video , brought a pull on my heart watching !
Thank you Gordy and Gavin.
Gordy Gritters, thank you for sharing your knowledge!
Merry Christmas Gavin thanks for the video very informative I hadn't thought much about Bolt Woble Factor?
I just completed Gordy's week long precision rifle building class as well as his AR accurizing class. You won't meet a better person, and the classes were worth every penny. He allows you to take pictures and video for personal reference and even makes himself available for phone calls and assistance to all his former students. He says he just considers it part of the cost of the class. You're not just taking a class, but building a working relationship with one of the best in the world, and he genuinely seems to enjoy teaching. I was most impressed whenever he responded to questions. No question was insignificant to him, and every response was like opening a book on the subject. He's a scientist who's always experimenting to better his methods, and he possesses not only the knowledge but the ability to teach it too. Did I mention that he's also patient with the novice? I highly recommend. However, do yourself a favor and read his book first prior to the class so you're somewhat familiar with the concepts. You'll get way more out of it that way. Highly recommend.
Great summary! Agree with all of the points you made. Gordy is top shelf!
@@Ultimatereloader Thank you Gavin for letting me know that Gordy was out there. The funny thing is that I used to live about 40 miles from him and didn't even know it. Now I live a few states away, but it was worth the trip. Btw, did you ever eat one of those crab cake sandwiches on lunch break? Sure wish I had another one.
I've worked underground for 28+years in a coal mine. It would be alsome to have a shooting match underground. Great video, great info.
To me the advent of CAD/CAM design and manufacture has given us an astounding level of precision in rifle components and scope components.
Add to that innovations in design and materials like great new reticles and carbon fiber wrapped barrels just to name a few and we have almost unheard of accuracy even from very reasonably priced rifles and scopes.
Finally, today's factory match ammo has also benefitted greatly from CAD/CAM precision bringing even more accuracy.
And for field use and PRS competition at unknown distances advanced ballistic engines slaved to environmental sensors (KESTREL 5700, for ex.) combined with laser rangefinders make accurate firing solutions more and more precise.
Now if we could just improve the nut behind the trigger. ;o)
Lots of great stuff here - thanks 🙏🏼
Good day Gavin... I'm finding these gunsmith/accuracy videos VERY helpful. Thank you for you time and effort to create these. Would you possibly consider making a video on HOW to check if your muzzle has "opened" up, possibly creating accuracy issues? I can't find any info on this topic on the net, and this video sparked an interest on this topic. Thanks
Definitely looking forward to more videos centered around ultra high precision. Keep up the good work!
Great video that man seems like a heap of noledge and is good at conveying it. I hope to continue to see him on this channel
Gavin, I appreciate you so much brother ‼️ 💯🤙
Thanks Gavin
6 more hours of Gordi please.
Good information and video thanks for sharing.
Awesome video...super interesting!!!
When I worked at Remington in Huntsville we had a 100yrd & 200yrd indoor range. Definitely very nice for accuracy testing. We had to pack up & use local outdoor range if it was down for maintenance.
Marshall - why doesn't Remington has an accuracy guarantee?
@gavintoobe when you test the barrels you threaded to see if they have opened up, please make a video on that process. Thanks
Awesome!!! The "BIG-5".....very true.
There be (entertainment) gold in them hills!
How about a 6.5 Grendel ignition study?
Firing pin protrusion vs MV SD. Turn down (to lengthen) under the bolt tail contact surface or grind tip (to shorten) five SS pins across the spec. range from 0.028 to 0.036”, inclusive.
When I was younger I knew a man his last name was Swartz that built a.222 cal. Rifle that just enlarged the first hole by thousands of an inch. It was amazing how accurate that it was. A lot of things go into achieving this.
Hola desde España me encanta tu programa lo siento muchísimo no saber inglés pero no me pierdo ningún video animo sigue así

I love Madrid. Me encanta todo Espana.
As someone trying to get into fun (not necessarily competitive) long range precision shooting, this video is right up my alley. I have, as a primary hunting rifle, a savage model 11 chambered in 308win. I am poor, so I have to be very careful about where I spend my money. I reload, and I have explored and used chrony data to do load development with focus on case prep (fireforming, FL shoulder bumping, measuring jump to the lands, ensuring concentricity, etc) and have worked up some fairly decent ammunition for this rifle. What I would like to know is, where to go next? Obviously, I need to get up into better projectiles, powder combinations, and keep doing the accuratizing that I can do on the reloading bench and at the range with the chronograph. What I'm most curious about is: if I have to do some work on the rifle, where would I be best (and cheapest, as you say low hanging fruit) directed? Better barrel? Bolt lug machining? Different stock and/or bedding? Different scope? I'm using stock hardware; nikon bushmaster 3-9x40, bog standard stock, as far as I know no bedding. What steps can I take inexpensively, on my bench at home, to further accuratize this platform? Thank you so much for providing this content. I know I'm asking a lot but I'm not demanding an answer. If you have some thoughts and want to reply, awesome! If you get a lot of similar questions and do a video on the subject, awesome! Thanks again and keep up the good work!
Effects of action to bore concentricity on bullet jump would be a great topic.
Another request for recommendations on barrels Gordy works with.
Thanks for a good video.
Gavin, info on lapping lugs on savage and Remington. Info on barrel crowns as well as far as how to recognize a bad one.
A barrel crown has 2 main factors. It must be burr free and concentric to the bore.
Good job G
How about some discussion on rifle building and accuracy for the 22LR?
what about tuners and tuner-brakes..Are they worth the money and ntime if your rifle is shooting really well before.?I loved this video.Thank you.
Another video with Mr Gritters ???!!! I have his book, very usefull if you wanna build your own custom rifle one day.
thank you for this video and MERRY CHRISTMAS !!!
YES! And another coming- troubleshooting rifle accuracy issues. Which book do you have?
And MERRY CHRISTMAS back at 'cha!!!
@@Ultimatereloader The book of Fred Zieglin & G. Gritters "Chambering Rifles for Accuracy", we have no books like that in France!
@@Ultimatereloader Have you discussed the ever popular barrel break-in voodo? Can that have any bearing on accuracy? There are 99 opinions and the manufacturers sometimes give you written instructions (for me it was DPMS) on the shoot one and clean it for the first 5, then every 5 proceedure.

On June 8th, 2013, Michael Stinnett shot a new world record, surpassing a group that held the record for 40 years. 5 shots were fired at a distance of 100 yards. This record was shot at the North Texas Shooters Association NBRSA match in Denton, TX. That 5 shots were fired was verified by use of a moving backer, and the .0077 IN group size was an average of the measurements from multiple judges.
Gavin, what size magazine are you using for the 300PRC in your chassis? Have you had any issues with the factory COAL being to large for the mag?
It'd be nice to try the 300m indoor range that's carved into a mountain like they have at Brunig Indoor in Switzerland, or the Muller Shooting Center in Ulm Germany that also has a 300m indoor range. It really sucks that even our most high tech/upscale ranges pale in comparison to Germany, Austria, Switzerland considering how popular shooting sports are here in America.
I had a set of quality scope rings where the rear ring wouldn’t tighten to the base (picatinny rail). It wasn’t sloppy loose, but you could move it forward and backward with light pressure. Cross bolt torque was correct, but the ring was still loose. Swapped the rings around (front to rear, rear to front), but the rear ring still would not get tight. A closer look at the pic rail showed that it was out of spec with taper front to rear.
This was a factory part on an expensive factory gun that even came with a “test target”.
I replaced the factory rail with a quality aftermarket rail and everything was good to go.
Had another issue with a hand-tight muzzle brake. The rifle shot poorly until it got hot and the groups tightened up. Let the gun cool, groups opened up. When the barrel got hot end expanded, it would tighten the brake, cool barrel and the brake would get loose, which caused the issue.
Bottom line: details matter, assume nothing, learn how to check EVERYTHING.
Very informative! Interested to see how these topics get broken down in more detail.
Merry Christmas all
Thank you.
1000 yard bench rest record. 1.068", 0.102 MOA, Mike Wilson, I found the story over at accurate Shooter dot com. Warning the sight is a very deep rabbit hole of good information.
Damn... Thanks I'll have to check that site out.
You mentioned learning how to slug a barrel, will we see a video on that in 2020?
Yes Please show how to slug a barrel.
I just can’t find a common ground on barrel tuners for centerfire rifles, do you have any thoughts on that subject?
I'm not a benchrest shooter, but I realize that when it comes to reloading, rifle builds, etc these are the most accurate shooters out there. So therefore, I look to them for info on reloading, tips and tricks, etc. If these guys shoot in the 0's at 100 yds then they must know a thing or two about reloading,
How about a series on precision shooting step by step? I'm talking selecting components, chambering, bedding, cleaning, reloading, etc. Start to finish WITH DETAILS!
Like I said, you don't have to be a benchrest shooter to appreciate the accuracy that can be carried foreword to PRS, hunting, etc.
it's pretty irrelevant to any practical shooting though. the difference between an 1/8 moa gun and a 3/4 moa gun when shooting past something like 600 yards is pretty much a wash when it comes to hit percentage. ammo sd (yes, i realize that can be part of what you're talking about with benchrest reloading, but it's not the same. benchrest guys reload their ammo right there at the range as they're shooting.. they can tend to make ammo that wouldn't be reliable in any sort of real world scenario), reading wind and conditions, and fundamentals are way more critical to hitting at that point.
@@bjornegan6421 I wouldn't say it's irrelevant for practical shooting at all. You want to know that your misses are because of you and not your tools. Confidence in your tools makes practicing fun, and the right kind of practice will make you a better shooter. I haven't met many shooters who didn't want an accurate rifle, regardless of their application. Also, most factory guns don't shoot 3/4 moa - if only they did! It's like playing the lottery; you may or may not get one that will do what you want it to do when you make the purchase. Some folks collect a lot of firearms over the years but never do get one that will shoot sub-moa, let alone better than that. Gordy actually teaches a class on accurizing factory rifles that I highly recommend. It's a lot of fun ... and practical too.
@@davidhutchinson6108 it's not relevant for practical shooting. i'm posting a link in this comment, but if you dont want to click on it because i could be posting something malicious, then google: How Much Does It Matter? Overall Summary precision rifle blog. it was posted june 9 2015. it is a summary of the entire study which has more pages if you navigate. it's based on Bryan Litz's (applied ballistics) research. you'll see that the difference between a 1/8 moa and a 3/4 moa gun dont really increase or decrease your chance of hitting a target past x yards. this is why i said what i said. it's not only my opinion, it is substantiated with actual scientific study and real world experience involving military application as well as knowing some of the best shooters in the world and what they think. precisionrifleblog.com/2015/06/09/how-much-does-it-matter-overall-summary/
@@davidhutchinson6108 2nd reply to your reply.. with that stated, it is nice to have as accurate a gun as you can get. faith in your equipment is nice to have. in some environments, such as f class, and most definitely benchrest, you'll see edges go to the people using more accurate rifles with better loads. however, the winners in f class usually won because they had more favorable conditions than everyone else and were on their game better than everyone else over the competition. as keith sanderson says, it's not who's the best, it's who's best that day. it's a mental game as much as anything. reading environmental conditions and consistent ammo plays a much larger role in hit percentage in practical conditions than anything else, especially a few fractions of an inch of moa measured accuracy. i'd rather have a 1 moa gun with a consistent load and good environmental data and range than a 1/10 gun with ammo that is inconsistent and unknown conditions and range.
@@davidhutchinson6108 the link i posted has the previous parts of the article posted near the bottom. most relevant to what we're talking about is 'how much does group size matter'. precisionrifleblog.com/2015/04/15/how-much-does-group-size-matter/
as you can see, if you look at it, not a lot. even though i said i'd rather have a 1 moa gun over a 1/10 moa gun, given better ammo and known factors with the 1 moa gun, i'd obviously rather have a 1/10 moa gun with the same good ammo and known factors.. i'm just trying to make a point.
thanks so much to learn cool 👏
Do a video on bullet jump and accuracy. How far from the rifling can you go and still have small groups? With the cost of barrels, it would be good to know methods that shooters can do to get the most out of their money.
That’s really rifle, cartridge and bullet dependent. Not really something that can be meaningfully measured
Oh I had a video idea that might be helpful to a lot of new and even experienced hand loaders. Discussing cartridge pressure and the relation between case capacity and jump / jam. Specific that by seating the bullet out long enough, although you are gaining case capacity, you’re reducing freebore.
I found a great load for my lr308 with about .015” jump and was looking online to see if I could bump up the powder charge a tad since I had gained a pretty good bit of case capacity by seating out longer than the published data I was basing my load on.
Apparently the pressure can spike quite a bit as you remove freebore? One guy was saying the pressure can spike as high as 7,000 psi if you get close to the lands, touch, or jam compared to the same powder charge but with like .050” jump. To me that seems a bit high but I’m still learning and this whole concept is completely new to me.
I understand how to slug a barrel but would like to know how to identify if the barrel opens up I assume at the muzzle end....a video would be great thanks....
I would like to know if you or him would recommend a carbon six carbon fiber barrel for a tikka t3x tac a1
I learned this in the 70's watching my dad learn gun smithing from RON Freshour in Texas City Texas. That man was a master machinist to the level of tool maker.
I have a few questions. I’m looking to get into a rifle for what I’d like to call precision hunting. I’m looking for a gun that can pull double duty. Shoot 800-1000 yards accurately and put down a deer precisely at that range. My budget is around $1000 all in. I’m looking at a savage 10 with a heavy fluted barrel with the accutrigger. Found an excellent price that affords for 3/4 of that $1000 to be put into the scope. Is this the way you would lean?
Most new bolt action rifles will shoot under 1" groups at 100 yards, if you handload with good* components most of them will shoot closer to half an inch if you do your part. Spend your money on a good scope and on handloading equipment and you will have a good shot at making most any modern bolt action capable of hitting a deer humanely at that range... however... for most shooters that haven't played out that far much... they are the weak link. Practice.
World Record Group | McMillan Fiberglass Stocks. The world record for the smallest 100 yard benchrest group was shot in 1973 by Mac McMillan using a handbuilt prototype McMillan rifle with an early McMillan stock. The 5-shot groupis a mere 0.009” center to center and was measured with a 60x microscope for verification ...
Benchrest Shooter Posts Stunning 1.068” Group at 1000 Yards - New World Record! by Jordan Michaels on July 27, 2018.
Good Budget rifle = Tikka. Even the thin barreled Rifles are Shooting good, thats a sign that they do a good Job with there Actions and Barrels.
I bought a new used tika t3 223 with cold forged hammer sako stainless steel barrel and 1:8 twist... the gun is so accurate I could not even believe it. Even with 55 grain bullets.
Later I started to better understand why... stainless steel rifles can be as much as 30% more accurate than blue rifles (Wayne van zwoll).
.
Plus the rifle has a composite stock and it came with a 1 pound target trigger.
The scope is a 16x covenant rifle scope from Cabellas.
I shoot quarter and half dollar size targets at 200 yards and penny size targets at 100 yards.
@@firetip198 We sell a lot of Tikkas, Light, CTR, Tac/a1. I look at the locking lugs if i clean the barrel, they Always bear on both lugs on most of the Surface. Its a Little better to see on blued bolts.
We also sight them in, never had a bad one. Not even the thin barrelled are picky with ammo.
@@firetip198 the materials used are a very small part of the accuracy. it's the precision of manufacturing that makes more of a difference.
@@marinioaweischo6614 in short actions, a well made light barrel is usually just as accurate as a well made heavy barrel. however, when shooting longer strings of fire, the heavy barrel will most likely stay more accurate than a thinner barrel. i've seen pencil barrels shoot .25 moa groups. i've seen heavy barrels shoot 3 moa groups with good shooters.
Which barrel is recommended?
I think it'd be a good experience learning how to accurize a milsurp without turning it into a sporter build.
Well, I do have that planned for "some day" :) :)
See, what you want to do is take a nice Yugo sks and get yourself a Tapco stock and one of those receiver style scope mounts like the ak uses... lol
As I listened today 9-17-2021, this was about accurate Bolt Action Rifle Shooting, so lets make comments that pertain to the use of commercial or custom bolt action rifle building.
I'm surprised he didn't mention projectile selection when listing the 5 most important things influencing accuracy.
I know this isn’t technically part of the rifle and I’m not a benchrest shooter(I’m a PRS type shooter) but I believe ammo is most important after barrel and trigger.
awesome
Just proves to compete at high level you need to be RICH
WTF does Gordy know about building accurate rifles?
EVERYTHING!
Interesting video. While I have no intention to enter matches of any sort, I do like my rifle to be as accurate as possible, I'm still the wild card in the equation. My rifle is a Ruger American Predator in 6.5 Creedmoor in a Magpul Hunter Stock, Vortex Viper HSLR 4-16 X 50. With handloads I've gotten just under 1/2" group @ 100 yds. So, yes you can do some reasonably accurate shooting on a budget.
1/2" groups at 100 yards with hand loads?! That's pretty "typical" with most factory ammo out of a predator from what I've seen in the forums I'm in... What's your load you're using? If you're using 140gr or heavier I'd expect around 1/4 MOA with a hand load?! Have you been over cleaning it with copper solvents like Hoppe's #9 ETC each time? They like to shoot "dirty" with copper fouling for several hundred rounds before using any solvents, copper fouling increases accuracy to a point. Just use some occasional oil like Breakfree CLP until your groups open up somewhere around 500-700ish rounds and THEN use a copper solvent. With the factory trigger set at 3 lbs I get .3 MOA groups with factory loaded 143gr ELD-X and 147gr ELD-M and 1/2 MOA out of everything else I've tried from Hornady. I only did a mild break in, cleaning between the first 5 shots with CLP and then let er rip and haven't cleaned it for 234 rounds now besides an occasional patch of CLP for long term storage or if I get rained on.
@@macgyver5108 Thanks for the info. I used a copper solvent once after the first 100 rounds, then CLP after each range session . I'll try letting it get "dirty" and see what happens. I've got some 140 ELD's loaded up with 41.9 Gr of H4350 and COAL of 2.280 which is where the "best" group. Don't have a chronograph so velocity isn't known. I've heard that the Ruger's like a generous jump to the lands, so I'll be trying some different seating depths. What has been your experience?
@@timmartin6410 Yeah, skip the CLP all together until you plan on storing it over winter or get rained on ETC. Since you've cleaned all the copper out it's going to take about 20 rounds just to get it to group "ok" again and it probably won't start to shine until around 50-100 or so rounds. I've just decided I'm going to revisit doing a more thorough break in on mine of shoot, then clean the copper after each shot for 10 rounds, not for accuracy gains which most people think happens but for corrosion prevention. Little pits and scuffs in the bore get covered by copper fouling and can create air pockets that can corrode if you don't do a break in...
As for your load, I haven't messed with my 6.5 yet but I used to reload for my .308 a few years ago. I'm at 234 rounds and when I reach 300 brass kicking around I'll start reloading again. Need to buy a new reloading kit because I used to reload at my neighbor's who has passed away now!😕 Your COAL is a bit shorter than Hornady's factory loads which I've been getting great results with at 2.812". My best results have been with the heavier bullets in the factory loads though, my rifle really likes the 143 ELD-X and 147 ELD-M's.
Definitely recommend getting a chrono for load development though because you're working "blind" without knowing your actual velocity, especially for long range work. With a chrono you can use the "Satterlee" load development method to find your ideal node(s) in as few as 10 shots! You load up 10-20 rounds all using the same lot of brass in .1 gr increments and record each chronograph reading looking for a "flat spot" in the pressure curve as you increase charge weights and that's where your node is, then you can play with the seating depths to fine tune for your best accuracy. One major note on most copper solvents too in case you weren't aware... HOSE the bore with something like WD-40 or CLP after using most copper solvents! They usually contain ammonia which will PIT your bore if left in there to dry without being displaced with oil of some sort...
@@macgyver5108 Yes a Chrono is on my list. In my previous reply my load should have said Hornady 140 grn BTHP, not ELD and I miss typed my COALtoo, it should have been 2.850. Senior moment I guess. After using any Copper Solvent, I usually soak a patch (or 2) in Alcohol and run it through the bore to clean out the solvent, then follow with CLP. Living in AZ I can still get out to the range in "winter" since the days still hit in the 60's.
@@timmartin6410 "Jealous!" I'm in WASHingTON, the ever-wet state... The only difference I've seen between the HPBT and ELM-M is at greater distances because of the better B.C. with the M's.
Please explain the difference between accuracy and precision. If anyone you should know it would be you!
For shooting: Accuracy: Is the group centered on the bullseye? Precision: Is the group small or large? The term "accuracy" is sometimes used when people really mean "precision"- so I sometimes use the terms interchangeably
Imagine two scenarios, one has a group that is three times the size of the other. Now imagine the example of the smaller group being aimed at a bullseye and that group shot fall is very far away from the bullseye, but did it’s thing and printed a small group. At the same time, imagine the example of the group that was three times larger than the other, but that group when aimed at that same bullseye is perfectly centered on the bullseye.
Those two outcomes are very different and we define the one that is a smaller group as better precision, but the other one which is centered on the bullseye are more accurate.
Sometimes we can have both, but sometimes it is accuracy that matters more. When we have sighters and there is no worry about a cold bore shot that is way off because we can walk it in, that is a scenario where precision alone will suffice. However, if you don’t have an opportunity for sighters, and the cold bore shot can be way off, then the discussion centers on the factors that affect accuracy. In most circumstances, the first goal is precision, and when pushed very hard we can also achieve accuracy.
Simple, precision is how small is the group your rifle can shoot. Accuracy is putting that group where you want it to go.
I feel like hed be a good auctioneer
I never dont see a reply from Gavin?
Take a look at Saeed al Maktoum’s 100 yard indoor range.
But he does shoot a 577 T Rex in it for laughs.
Can I entice you build a 224 grendel please🙏 let's make shit happen
i have often wondered why i've never heard of an accurized .270 win? is there a specific reason for this? or has it just slipped everyone's mind?
i love your channel, by the way
.270 is great IF you hand load for it! Really needs to be shooting 150+gr bullets for their higher B.C.'s though... The biggest issue is it's a long action cartridge which doesn't burn as uniformly as a short action cartridge, which is why 6.5 Creedmoor is so popular now. Short "fat" casings burn a lot more uniformly than a long casing which gives you lower deviation numbers. That's why the .308 blew the 30-06 out of the WATER in 1000 yard competitions when it was introduced back in the 60's even though they both shoot the "same" bullets, so much so that they had to reduce the size of the NRA 1000 yard target's X ring to prevent all the ties in competition that were happening!
MacGyver- thank you for the explaination. it makes sense now. Is this the reason for the .270 wsm?
@@farmerbobsgarden5554 it's the reason for alll WSM and WSSM cartridges. Check out the .223 WSSM if you want to see a really crazy cartridge! Only drawback with WSSM, they have a shorter barrel life because of how the gasses move through the throat like a jet in comparison to a normal short action but they're extremely accurate! kjg-munition.de/5,6-mm/223-WSSM/223-WSSM-KJG-Photo.jpg
...
