Last year before I retired I bought a Savage 10 stagger feed 308 HB. It came with the factory Tupperware stock and 18" barrel. One of the first things I did was to get a 26" Shilen barrel from Jim and a Choate tactical stock. This barrel shoots lights out and is dead on at 100 yards. I recently purchased a 22-250 HB to have a switch barrel rifle. I have modified a barrel nut wrench to loosen barrel nut without the need of removing scope and picatinny rail. My question is how much of a POI impact should I expect when the 22-250 barrel is screwed on?
