I could believe the barrel needed some rounds to smooth out.
I’d also wonder if it’s WW or Federal ammo. Had those same issues with my 270 WSM back in the day.
He's tried Nosler, HSM, Hornady, Winchester, Remington, and some other brands as well. I believe it is most types now that are giving him issues after about the second firing. He's been using Hornady precision hunter as of late.. I'm sure the barrel was rough, plus maybe the bedding was not perfect. After firing that many times in a row, it settled in.. He said he was "either going to burn it out, or it was going to shoot better afterwards". Funny thing is he had to have "new" at the time. I tried convincing him to buy a used rifle here that Josh303 had for sale that was s confirmed shooter, but he didn't want to have anything to do with a "used" rifle. Some people man... I love buying used rifles. I enjoy working on them, fixing them up and accurizing them..
