I shoot a Benchmark 1:8,26" bull barrel, I had a PTG reamer made, it is a .272 no turn neck, .073 freebore, I shoot 87's-108's. This reamer was showcased in gun of the week. I can put any of these bullets anywhere in the case neck and all shoot good. I also had a Harrells die made. The barrel really likes the Berger 108's, 29.5grns of IMR 4895. It also likes the Berger 105/Varget combo, any other ?'s just ask.
