Im looking to have a 2nd saum built up for competition. I want to get your opinions on barrels be it gain twists, 8 or 8.7 twist, or anything in between. I have always used 130s in my 9.5 - 8.5 gain twist and had good luck at 3100fps. I would like to use 140 hybrids in this rifle. Ill be using the 296nk 120fb reamer, that seems pretty common. Any input is welcome since therenare a lot of shooters well versed in the saum game by now. Thanks.
