Default How many "warm-up" shots before rifle settles?

I've been noticing my Rem 700 takes about 15 "warm-up" shots before the barrel settles in. Is this typicall as it seems excessive. It goes from 2.5" groups and settles in with 1-3/4" groups once settled. Is their another system of procedures that I should follow?

Are you cleaning the barrel before every outing?
If so, maybe stop.

What kind of barrel? I light profile barrel OPENS up after 15 shots.... I'm guessing you have a heavy profile.

I rarely clean my bolt guns, especially my primary hunting rifle. I generally don’t shoot more than two rounds during hunting season and maybe 10 rounds just to make sure it’s hitting before season opens.

On each end of the extreme.
After a good cleaning my Ruger 7 Mag takes about 20 rounds to settle down and group right.
My Win M70 375 H&H takes 2 rounds.

Not cleaning too often and its a heavy 5R barrel from Remington. For some reason it likes to be fairly warm to the touch before the groups come together.

a 3/4" shift in group size is more likely you when talking about a group that size. Unless it's a 300 yard group. Your rifle should be shooting well under 3/4" at 100 yards with a tuned and tested load.

I don't say this in jest but know one knows how well you really shoot but you.

My rifle same as yours Rem700 stainless 5R. If I do my job and I get warmed up dialed and settled in the rifle will shoot one hole groups at 100 meters all day long. and that "warmed up, dialed in, and settled in" is all me. Nothing done to the rifle. it all me getting into the groove.

That said cleaning the barrel is your enemy Or over cleaning is. If you clean the barrel to the point that you get no more copper fouling on the patch you are going to need 10-20 rounds to foul the barrel. Thats what my rifle takes after a good cleaning.
After about 600 rounds give or take I'll do a light cleaning to knock the rocks out. three or four passes with a brush and solvent and patches till dry, followed by a few oily patches and a few dry patches. This removes the vast majority of powder fouling and a minor amount of copper. My barrel doesn't really copper foul anymore but there again it has over 2000 rounds logged. Yes logged. (You should keep a log of dates, rounds fired and dates that you cleaned the barrel.) At this point I can be sure that my rifle will group about 5/8" until I settle in and start shooting one hole groups. Point of impact vs Point of aim is off about 3/4" but I don't adjust my 100 meter zero. I don't worry about it as i only use 100 yard zeros for load work up.

Now you never mentioned how you shoot. as in position and support. Nor did you mention loads used as in Factory or factory match or tuned reloads. And no mention of what you are capable of doing. I got a brother That would be lucky to hit the paper target at 100 yards even with my rifle.

Edited as op stated 3/4” to 1” groups below.

Keep working with that rifle and you’ll likely find it can shoot a lot better.

The reason i am pointing to the gun is that my 223 rem 700 does not do this nor does my 308 savage. It only happens with the Rem 700 5R in 308. The gun is being shot seated with bipod and rear bag. Also I meant 1" to 3/4" groups after it settles in. I have recorded 1/2 groups with 3 shots and the 5 shot groups are doing 1" to 3/4 inch once settled.

Have you tried cold bore and warm up with FGMM ammo?


Also, have you tried a 10 shot dot drill?

That is certainly not "settled-in" for a 308 5R. If all your other rifles shoot better as you say, then something is "loose" such as scope, mount, or action screws.

Well if everything on the gun is good as in everything tight and torqued properly etc. then that is 100% you and your recoil control. shooting a bipod of a bench it's hard to get a good body position and control recoil. You should try a prone group, squared up behind the gun, with a sligt loading of the bipod. bet the groups get better.

You never mentioned the trigger. if it factory that can be a huge effect on your group size.
