Most people I encounter who have trouble shooting Good groups either don't have their barrel floated (most factory stocks especially rugers have warped stocks that pinch the barrel.) Or they rest their rifle on the barrel causing the harmonics to be off. Simple stuff.

I used to have very poor accuracy from a bench with my 16" 1 to 8 twist Ruger AR 556 but was due to my poor inexperience. I used to rest the barrel on the front bench rest instead of the hand guard the barrel runs through and I would get such poor groups at 100-150 yards and for the longest time I thought it was due to something being wrong with my barrel thus leading me to over cleaning the barrel after every use, "not to the point of damaging the barrel, I always used nylon brushes with a bore guide". One day I was at the range trying different ammo in my AR seeing if that was the issue and a fellow shooter happened to see how I was resting the barrel on the front bench and I guess he could read my frustration and decided to walk over and discuss with me how what I was doing was a horrible method when it came to gathering groups. The reason I put the barrel in the front rest was because of a third party grip I used on the front portion of the hand guard which didn't allow for me to reliably set that portion of my rifle in the rest. He helped me take the handle off, got out his nice range spotter and took the time to work with me in understanding ballistics vs platform and other things but after removing the front grip and resting the hand guard portion on the bench rest I had almost immediate improvement on my groups. It's crazy how such a simple thing was overlooked by me and I'm sure there's others out there that are struggling with the same issue. I'm so grateful that kind man took the time to help me. After he said his goodbyes and I thanked him over and over he left and I've never seen him again. Every time I go to the local range I hope to see him there just so I could thank him again lol! He personally improved my range time enjoyment tenfold.

@@allywilkeforsenate depends on the ammunition you're using as well as keeping a clean chamber but DON'T over clean the barrel.

I love the process - for me I always start with me. I found that coffee before a range day is not a good combo with high magnification optics. Also, sandbag up front and sock full of rice in the back. one rifle needed a compensator. then i research twist vs projectile weight. it's incredible how different barrels like different projectiles. then i try different ammo. lastly, if using an optic, checking scope mounts - twice in my life did I find that the scope wasn't torqued to spec which is why I always bring my Wheeler Fat Wrench when zeroing in a rifle for accuracy. thus far, this has kept me happy with my repeatability.

@@jaydunbar7538 You are high. You can take an average machinist and he can EASILY build an incredibly accurate rifle. These are easy and basic operations down to about half a thou or ten thou.

[@endutubecensorship]

Rifle shooting inconsistently? My first go to is to check *ALL* the screws are torqued properly. Stock/base/ring screws can get loose and cause problems, a bit of *blue* loctite and a proper torque wrench can cure a lot.

[@twintwo1429]

If I could get this rifle so shoot a 2 1/2 group at 100' I would be so happy. I don't think it can

Seeing these comments about shops and mechanics is exactly why I left the industry. Too many bad shadetrees, giving us real techs a bad name. When you take your car to 5 different shops, and nobody can figure it out...I was the last stop you had to make. That story was very common. It was a good hobby, but not a great occupation, nobody appreciates a good mechanic these days, especially the shop owners. That's why it's tough to find one that isn't too busy to help you. Unfortunately, even if you get the best grades in tech school, or flag the most hours in the shop, and have little to no comebacks, you're still in an industry where it is not required to have any education, and in most cases, any certifications. But, thanks for the video. Hope you find a good tech someday.

After 40 years in the industry I can absolutely agree John B. Quality 'Technicians" are few and far between.

[@Midwesternlifestyle]

As i had this video playing i was measuring a barrel nut with a depth mic. I got a colt AR-15A4 to clone the M16A4 and had accuracy problems since i bought it 3 years ago. I just didn’t take it out enough to really test what was wrong with it. I thought it might be me, maybe the ACOG i put on it was defective. Then i realized i was getting a consistent 10 MOA vertical string with only 4 minutes of horizontal spread. I wound up removing the knights handgaurd, shooting off a magazine and shooting my M4 clone right next to it with the same optic swapped from one rifle to the other and finally proved it was the gun. Colt customer service refused to take it so i decided i had to pull it apart and look at it myself. Fit between the extension and upper is fine, the face of the upper threads looks fine, the barrel nut measures flat all the way around on the inside so the only thing it could be is the bore. I don’t own a bore scope but i can clearly see, looking through the chamber end with the barrel held upright, there’s a dark spot in the lands about 3 inches before the gas port in the upper left hand corner of the bore. I can safely say i have a blemished barrel, but the problem is finding a suitable replacement when A2/A4 barrels with all the proper features, specifically cold hammer forging is difficult when this barrel length and profile is obsolete. The best thing i can find is surplus that comes stripped and undrilled for a front sigh base which means i’ll either have to outsource the work, or buy the equipment to drill and ream taper pin holes to finally have a functional M16A4 clone.

[@dannyboy5272]

I bought a Desert Tech MDRX 223 with High Hopes hoping that it would be an accurate rifle. Took it out and shot it, and the accuracy was horrible. I sent it back to Desert Tech. They called me and explained that the rifle was within spec. They sent it back to me, And I continued to try different loads in it. It still shot horribly. I screwed a reflex suppressor on the rifle. My accuracy increased, not by a lot but it was noticeable. I shot the rifle without the brake on it. The groups were just as horrible as with the brake on. I machined a barrel tensioning tube and installed it on the barrel. My groups shrunk exponentially. The rifle is capable of great accuracy, but the pencil barrel that Desert Tech chose to use on this platform in order to cut down weight on an already heavy rifle, was very, very detrimental to its inherit accuracy. I went from shooting inch- inch a half, to 2 inch groups at 50 yards to shooting one hole at 50 yards shooting 1/2 inch groups at 100 yards, instead of five and six inch groups at that same range.

[@randomidiot8142]

Tensioned barrels will get more popular as time goes on and people figure out the benefits on lower end guns. Most of my airguns I've done have tensioned barrels for a reason; harmonics and soda straw barrels don't vibe well.

Had issue with a sako L461 (vixen) in 222rem. Found the issue to be a loose set screw in the firing pin. And the protrusion was 0.124" on the firing pin. Adjusted it to 0.059" protrusion and set the setscrew back in again. The vixen has threaded firing pins. Now the ignition of the gun is much better.

[@aaronunterseher1627]

individuals should be actively trying to achieve that level accuracy. Gun owner regardless of your purposes can't be to accurate but can always be not accurate enough...

Does not shoot worth a damn in that rifle. If I switch to 90 federal tnt loads, it shoots exactly how I would expect the inherently accurate cartridge to.

I was banging my head against a wall damn near trying to figure out what the hell was going on with my 444 marlin Thompson Center Encore before primitive weapons season started last weekend and thought I was going crazy for a min... I would get my zero and take an extra shot to confirm and it would move and that happened a few times... A 444 isn't exactly a fun gun to shoot especially in a single shot rifle not to mention ammo is next to impossible to find. Eventually when I pulled the trigger I noticed the cross hair move inside the optic just from the hammer falling so I know it's moving around under recoil...

Thank you Gordy!! What a wealth of knowledge!! He brought up stuff I never even thought about. My big problem is still my Bergara B14 chambered in 6.5 PRC! I cannot get this thing to shoot worth a shit! I've literally tried every commercially available ammo out there. Including the ammo Bergera uses to test fire this rifle. With all due respect to Bergara I have not allowed them a chance to get involved with this situation yet because I've been in the process of moving for 8 months and just completed that. Thank you Lord! I watched your video about the muzzle brake, but did you shoot the rifle without it before attaching the can? I also have a buddy who has been an avid reloader for decades and he also has a 6.5 PRC he cannot get his to shoot descent groups either (Not a Bergara). Any advice would be appreciated. Thanks - Seamus

I find "the monkey on the trigger"... IE ME... Tends to be the majority of my problem. Once I started practicing a little more and found what OEM ammo my gun actually likes, not reloading my rifle stuff... yet ... I have no problem with sub MOA at 300 yards with a TC Compass II with Athlon Argos glass sitting on it. Before I start getting into PRS, I didn't want to spend a ton of money. Just needed something solid to get better with my skills first.

I've got a 6.5creedmoor. Was challenged to a 10 shot challenge by a friend. I can put 7 rounds on a .285 hole, but 8, 9, and 10 fly out to almost 3/4 inch at 100 yards. I've tried longer/shorter time between shots, different resting techniques, and several different load options within my database, but cant seem to get the full 10 in under a half inch.

Cleatus, Iffen it were me, i'd shoot those first 7 rds on the 1st day, then rds 8, 9, and 10 over the next three days, one rd per day, on that same target. I'd make dead-nutts damn sure those last three rounds were right on before i touched'er off. See what'cha got then. And just for S&G, i'd shoot 7 rds on a target, then switch to another target and shoot 7 or 10 rounds into it and see where she likes to shoot when warmed up. Now, that's what i'm ah thinking ...

[@VG-913]

If you can't get sub moa with a simple load change or floating your barrel or maybe a better scope. (Even reputable scope brands have entry level scopes that work great) then you're wasting time and money... anything past those 3 things just trade it. That means your gun is actually junk. That's flaw or defect and you're polishing turds at that point.

[@codyhummel2366]

If you ever have grouping issues the very first thing to check is basses and mounts. Still wont group swap out scope. Still not great? Grab some shells from the store. If you cant get at minimum a 2" group at 100yrds with factory ammo it needs some work. Hand the rifle to a friend have them shoot it. It might be as they pointed out all on you as a shooter

I put a Timmny trigger in my RPR and I didn't put the tension spring in from the original trigger. I would get a flyer every 3rd or 4th shot. After reading the instructions I saw where you have to use the original spring. Found this out the hard way at the PRS Absolute zero finale, my worst match to date.

[@smiley454jmw]

I would like to know how to make a mossberg rifle rifle accurate lol

[@texassportsman5880]

Let's first look at reasonable expectations. The average deer rifle is capable of MOA accuracy with over the counter ammo in a controlled environment. When you make it out to the field your accuracy will suffer because you're not shooting from a bench. Secondly, your average rifle is not a custom precision rifle where you'd use custom handloads. So don't expect groups the size of a dime at each distance. Thirdly, look at yourself. How familiar are with your rifle and scope. Do you have the discipline and focus to be that accurate marksman? Do you understand windage and elevation? Can you read the wind, the angle at which you're shooting, up or down angle. Can you accurately calculate and make those adjustments on the fly? So think about what type of accuracy do you reasonably expect based on your own abilities and the equipment you have or can afford. Once you know all of these items then we can talk about accuracy issues or perceived issues.

[@theremnant216]

VERY good points. I have had to adjust my expectations based on the fact that I don't yet have the knowledge or the experience to match the accuracy I see from some shooters on KZbin even with the same rifle, ammo, scope or other accessories. You make excellent points here!

[@texassportsman5880]

@@theremnant216 The average rifle and ammo that's available at your local gun store is capable of the accuracy necessary out to 400 yards. The kill zone of the average deer is about 12 to 13 square inches. Any hit inside will bring down a deer. In theory and practice you wouldn't need groups the size of a quarter for deer hunting. You have a large margine to err and still be successful. My setup is a Browning X-Bolt, .30-06, Leupold VX-5HD and $19/box Hornady American Whitetail 150gr PSP. This gets me groups the size of a half dollar at 100 yards. More than adequate to kill a deer. I need to practice from a prone, sitting position and using a tree and shooting sticks to rest the rifle. The group will open up because it's easier to keep a rifle steady from a concrete bench than from those positions. As long as I can place a shot inside that 12 to 13 square inches I'll be successful.

[@jrburge4674]

a Zastava M48 commercial action, 7x57. Douglas XX barrel 1/10 twist. I believe the trigger is a Boyd? It is set a 2 lbs and breaks clean with no overtravel. Can't remember exactly the brand. Leupold steel standard 1 piece base with Leupold steel rings and a Leupold VX3 scope (scope has been attached to other rifles both before and after, and holds zero perfectly). glass bedded into a Boyd's laminate stock. Cannot get consistent groups. Been handloading for 30 years. I've used from 120 grain cup and cores to 175 partitions. Homogenous bullets as well. Experimented with seating depths from .001 off lands to book length all in .002 increments. Powders from IMR4320, H4350, IMR 4350, IMR 4064, Varget, Big Game, Hunter, Reloder15, 19, Norma 204, MRP, W760, and more. I have put over 200 different loads through it. I don't scrub the barrel. I use Wipe Out and Gunslick (when it was still being made). I have a bore scope and check periodically so that when I want to get down to metal I am certain I am there. I do use nylon brushes from time to time when I see a lot of carbon fouling. I shoot off a front and rear bag. I've been a competition rifle shooter since 1992. High Power and CMP. I cannot for the life of me get consistent groups. It will shoot factory Hornady Superformance 139 GMXs consistently at 1.25". Will it kill a deer? Absolutely, and it has killed many. However, I saved for years to have this rifle built and since I doesn't have consistency, it has fallen out of favor with me and honestly, it saddens me. I have other Mausers that shoot very well. My accuracy standard is 1" averages or better. I actually have many Mauser rifles that hold this standard, with ease. I hold the velocity to "if it ain't broke don't fix it" 7x57 standards: 140s at 2700, etc. Any advice will be greatly appreciated.

Title: 338 Lapua Advanced Reloading, Part 12 Channel: Quarter Minute Magnums Q.M.M. Time: 7:49 He goes on for a few minutes about barrels and how some are just different, even within high-quality manufacturers, 1 or 2 out of 10 might be bad. It may not apply to your situation, but his point is that with all of the variables, it could be any one, or combination of multiple variables that the gun will just never shoot. With all you mentioned in your post, it's clear you have considered many, if not most. You could still find that one thing wrong with your attempts, but when it comes down to it, you just might have gotten a bad one. Best of luck.

I have an MVP from Mossberg currently in transit from a gunsmith because it was inaccurate after fitting a custom 350 legend heavyweight barrel.

I really appreciated what you do and all your material. I am having a nightmare with my Blaser R8. I purchased in back in early 2021 and have been struggling ever since. The plan was to purchase a 22-250 barrel first then move to a bigger bore. As stocks were low and there was issues getting them into Australia at the time I took what was on the shelf at the time. 300 Win Mag I have spent countless hours trying different things with reloading to get it to shot any good. I have tested loads at 0,018 jump through to 0.050 jump. None of which really seemed to work. The rifle seems to kick, twist and jump to the right. After trying this over some months my 22-250 barrel arrived. I stopped testing with 300 Win Mag and started with it. Again I tried from 0,018 jump to even more crazy jump. I found that Remington box ammunition seemed to shot the best so started testing at factory jump which was out at 0.120 jump where it seemed to work. I have no idea where to go with the 300 Win Mag and would like to know if anyone else has expirenced a similar issue with the Blaser R8.
