Ruger American Predator 6.5 Grendel first shots - not happy ( getting better)

[Osage1978]

Took the rifle back out this morning after relieving the stock some along the barrel channel and double checking everything was tight. I also scrubbed the barrel with JB's & wipeout again, not much improvement but some. The largest group being 1.125" & the smallest being 1" even. I think I was not following through with the other shots well last time so I'm unsure what made the slight improvement to be honest. It's shooting accurately enough to deer hunt with at the ranges I shoot but once different ammo arrives we'll see if there's something else it likes better. One group was only 4 shots because I shot a fouler first to rule that out

I just picked up the same rifle in 6.5 Creedmoor. The stock that comes on it is basically trash, especially if using a bipod and pushing into it at all.

Agreed, I'd get a Boyds but I'd have to buy the a. I. mag conversion kit for mine because it uses the AR mags so I'm looking at ways to make it work. I really regret not getting the 308

I've got my eye on these options:

Granted, these are inexpensive rifles, so it doesn't make sense for everyone to buy a $300-$400 stock to throw on it. For me, I think it's worth it given it's a hunting rifle and I plan to be shooting off a tripod or bipod in almost all occasions.

Are these all from the same session and same aimpoint? I'm assuming on every diamond you're shooting the white circle. And your 5 round groups are landing wherever? You are not adjusting anything each group are you? Aimpoint, scope, anything?

He may be single loading causing him to re-shoulder and re-establish cheek weld. This isn’t a good or consistent way to shoot for groups from a bipod and rear bag, especially if you are shooting from a seated bench position.

There is also the unfortunate possibility he has a Monday morning rifle and not a Wednesday afternoon rifle. Although, I wouldn’t give up on it just yet.

I asked because if he's not adjusting any knobs or doing any tweaking between shots/groups, he's just shooting 5round groups, then moving to the next target and 5 rounds and on, then with the groups moving like that and each group has a random kind of spread, it looks optical. Something looks like it's moving. I see this a lot in sights with mount quality or issues, bad torque values, jacked erectors, etc. There are things to do to rule it though.

I'm loading the magazine with 5 then shooting all 5 but the gun jumps so much at the muzzle I'm having to completely reset after each shot so I might as well be single loading lol

I am having to re establish cheek weld after each shot unfortunately, I am shooting it cross arm style so after reading your comment I'm wondering if hold the forearm may help?

So even if you are making large groups, they are still groups, although they have absolutely no pattern. Nothing vertical, nothing horizontal, they are just pretty random. The groups should not float around the aimpoint like that.
