[QUOTE="Hugnot, post: 3094965, member: 115658"] I am happy with a 8 twist 6 CM & shoot 105 Barnes Match Burners ( a good cheap bullet). If I wanted to include 112's or 115's I would go for a 7.5 or 7 twist. As seen below a 7.5 would do real good for 105's - 115's. I try to keep Sg values between 1.4 - 2.0. Miller sez subtract the length of the plastic tip, regarding it as weightless. Sg values calculated @ 35 F, standard pressure. A warm humid day in Indiana would boost Sg values up by 5% or so.
