So, I picked up a 10/22 T barrel a while back. Used, who knows how old. turns out, the box stock barrel shoots pretty good. coupled with a factory headspaced bolt that que did for me years ago. i had a revolution stock laying around, and a bunch of kidd parts in a factory trigger group. never expected it to shoot like this. 25y. SK magazine. the numbers on the top right, and bottom left i messed up. i was measuring a couple of targets at the same time and I think i transposed some numbers. or my dyslexia acting up.
correct measurements:
top left: .142", top right: .160" middle: .117" bottom left: .179"
