I bought the rifle used at Hendershots Gun Shop In Hagerstown, MD. They have a reputation for high end rifles, they did not know the round count. They could not tell me who smithed it. As far as groups I never took pics but could the next trip to the range. I will not lie, the life on the barrel is limited by how many I'm not sure but my guess is probably 500 rds.
Make no mistake this is not a gun you go out and shoot all day, if you want to do that go buy a 223.
This rifle shoots the 150 gr bullet at 3450 fps, w/ 80 gr of IMR 7828.
here is a pic of the bolt showing the trueing marks and lack of any pitting in the bolt face. The flash from my cell phone makes it look like brass in there but assure you there isn't any.
Even if the barrel was shot out, the stock, the trued action, the Redding bushing dies brass and bullets are worth more than I'm asking along w/ the three cartridge boxes
