[QUOTE="Alfred Crouch, post: 298007, member: 13464"] For 7 mm mags & 300 Mags - I think I heard a 26" length is needed to efficiently burn the powder. Seems I have seen that a 1:9 or 1:9.5 twist is desirable on the 7 mag. Remington 7 mag: mostly 26' barrel with 1 to 9.25 twist Savage 7 mag: 24" barrel with 1 to 9 twist Cooper 280 AI: 23" barrel with 1 to 10 twist What do you think the implications of these difference will be? Which would you think would be better? Thanks. Al Crouch [/QUOTE]
