Rifle grouping problems

[RifleBowPistol]

Yessir, the suppressor has no baffle strikes or noticeable problems. If it won’t shoot with the suppressor it’s useless to me. Thought about it but it’s a rifle I use for culling and refuse to shoot it without the suppressor.

For diagnoses purposes, remove the suppressor. If that's where the problem is and you don't remove it, you will chasing your tail for a while trying to find it.

The one time I had a gun do what that gun is doing, it was the scope, brand new top of the line Redfield back when they were great scopes. Some screws came loose inside the scope. It started shooting vertical strings, shortly after putting it on the rifle.

But since you have a suppressor on the gun and it's easier to remove the suppressor than to install another scope and get it all properly set up, bore sighted ECT. I would pull the suppressor first. If that does not do it, then try another scope.

I used to have a Remington 700 Varminter, that was made in the 80s, in 308. That gun would shoot .104" or so center to center five shot groups at 100 yards, with my hand loads. That gun still had the factory Remington BDL stock, and barrel on it. Eventually we had the trigger replaced with a Timney, other than that, it was a stock rifle.

Factory ammo, is not going to shoot that well, but should still be well under 1" at 100. I was using Nosler 168 gr. Ballistic Tips, with BL-C(2). I would say your bullet weight should be a very good choice, for accuracy in the 308.

Loose hardware likely wouldn’t be that repeatable or consistent in stringing.

Ours did, but it wasnt straight up like the OP. It went up and right @ a 45 degree each shot resulting in 5+ inches over a 3 shot group.

Checked the rings and all are in spec. The only thing I can’t check is the base unless I take the scope off. I’ve got another scope I’ll try, I’ll also take off the suppressor and try that. If none of that works I’ll send it off to get rebarreled and worked. That was the plan anyways, was just waiting on the barrel and hoping to make it to the end of MLD before I did it.

Maybe you just can’t shoot worth a darn. Too much or too little aiming fluid can also cause those issues.

I had the exact same issue years ago.

It was the screws in the rear scope base.

I was wondering when you’d show up. It ain’t my fault I gotta sit on a phone book on to use your **** shooting bench

holy crap .. that's over 6" spread and repeatable straight up and down ... i'd replace the scope your elevation turret is the only thing I see that could make such drastic vertical deviation only

I had a 308 that did the same thing and turned out it didn't like 150 gr bullets. Changed to 165gr and shot great. Hornady Superformance 165 SST.

My best guess is scope, then base... But like someone said above removing the can and shooting a group is the first and easiest thing to try.

I've had these issues a few times over the years and the only time I think it was the rifle itself was a 234WSM. Ammo was too dang expensive to "find" the problem, but I think that one was either really picky on ammo or just wouldn't group. I sold it.

Bedding problems, $$ on the replacement of floor plate needs a little bit of tweaking

Go back to Hornady, whitetail is the same as custom match, I had the same issue with my 243, couldn’t find it anywhere, then called Hornady and they said Hornady whitetail is the same as custom match and a little cheaper to boot. Also, I had a issue with my 243 with barrel heat. Try three shots in a row, nothing but a few seconds in between. Barrel heat makes my rounds start stinging upward like yours. It’s 3 quick shots, then see where your at.

My 308 was doing the same thing. Had a loose screw where the scope attaches to the action. You have to remove the scope from the rings to get to it.

Someone gave you bad info. Match is usually ELDM or BTHP. Whitetail is usually some form of soft point. Interlock etc.

OP I’d strip that thing down and retorque every bolt on it. Check the base. Check barrel contact. And make sure your front action screw isn’t putting anything in a bind. Also you may consider backing off to 55 in/lb. I run all mine at 55 even on heavy recoiling magnums. If it’s not bedded I’d get that done and have the dbm inlet checked. I’ve had several manners stocks with out of spec dbm inlets. Usually cut too deep. Easy fix. But will screw stuff up if not fixed. Manners QC is trash.

Odd question here, but do you have multiple suppressors that you use on this rifle?
