Went up to the range to squeeze off a couple to make sure everything was good after I relieved the barrel channel slightly. The rifle will do this with Barnes 300 gr. TSX too, but for some reason the brass won't make good neck tension so I am going with the Sierra 300 grain SBT until I can work on the 265 gr. and 300 gr. GS Custom bullets I have. I think this is pretty dang good.
That bullet hole is exactly 1/2-inch top-to-bottom and 1/2-inch left to right. My money was well-spent with Jim Brockman. Man I am tickled.
