[QUOTE="cohunt, post: 1520074, member: 94491"] Has anyone mentioned the land to groove ratio? You can have the same twist, same #of lands/grooves but each barrel maker usually has their own "proprietary" land to groove ratio. Not all "5r" barrels are created equal. Also, the heat treat/hardness can come Into play, and other "treatments" such as melonite can increase speeds too. [/QUOTE]
