I am getting fantastic groups with a max load of R#19, win primer, win case, and the Speer 100g BTSP is the most accurate bullet for my Rem 700. This load is unreal accurate at 300 yards, hard to believe that a non custom rifle can shoot this well. This Rem 700 likes the bullet jumping .040, and I bump the shoulders on the case after every firing, and have got 12 firings on the cases so far without trimming or full length sizing.
This barrel does not like Ballistic tips of any weight, but also loves the 87g Speer sp with a max load of R#19 also, tiny groups!
