Copper Fouling Question

[Lakenut]

Got out today and shot some 120gr nosler bt @3000fps. Figuring out the flyrs must be me. The gun REALLY likes this loading. When I did my part sub 1"groups were to be had. In fact groups were around .5 with one group being 1 ragged hole. Still had flyers now and then....always seemed to be on the 3rd shot of the group.

Shot 2 shots at 200 yrds and had 1.5" group.

Not going to clean until groups go south...but there us significantly less visible copper in the bbl. Guess things have smoothed out.

Nice

My Savage 12, 308 was a copper mine until I had about 300 rounds through it.

So what am I doing on the 3rd shot? Am I getting flinchy after the first 2?

How do you have the rifle supported? Your most stable shooting position is going to be sand bags up front and a rear bag. When shooting try to minimize the the amount of force you impart on the rifle and whatever you do impart do it consistently. I.E. use the same amount of force to pull the rifle in to your shoulder, do not touch the fore end, minimize the amount of force you apply to the grip.

You might also ask someone else to shoot the rifle for comparison.

Also, look into torquing your action screws, see the link below. http://www.accurateshooter.com/technical-articles/savage-action-screw-torque-tuning/

Have you tried multiple types of ammo to see what groups best?

Barrel warmed up and that changes everything.
You have to make a decision. If your a hunter, you want the cold bore shot to be on target.
if your a paper shooter, you want a tiny group and to get that you have to warm up the barrel.

3rd shot flyers with multiple loads. I am shooting from a bench with caldwell sand bags. Im trying to duplicate shooting position each time.

Man have I taken this thread off topic....

I have access to a lead sled but I haven' used it on this gun due to the stress it puts on the scope and stock. Should I give it a go?

I've never used one.

Have you tried shooting and then waiting ~5 minutes between shots?

Let a friend shoot it and see if the same thing happens.
