Re: worn spot on end of bolt
sounds like that is the spot that the extractor is pinned to the bolt nose, often times it will raise a small bump on the bolt noses' face.
The outside of the rivet will often times be touched on a grinder to smooth it off at the factory.
You accuracy problem. Could be the barrel needs a good cleaning, could be yopu over cleaned the gun with somthing you shouldn/t have.
Could be you clean without a bore guide. could be a scope base ring issue, could be stock bolts not as tight as they used to be. Could be about 20 other things including the driver, dif lot of ammo or powder. Brass necks work hardening ect ect ect. No one said any of this is easy.
