[QUOTE="MagnumManiac, post: 3040610, member: 10755"] I believe that a 7.5" twist is optimal for 77g-80g bullets depending on length and construction. A 8" twist may be perfect for the Sierra, but not all bullets are constructed the same. Look up Bergers twist rate calculator for that bullet. I will add, I have never found Hornady bullets to be match grade, their BTO numbers are all over the place and I refuse to use them, let alone spend money on them. Cheers. [/QUOTE]
