[QUOTE="noel carlson, post: 927296, member: 16138"] "I think maybe the question that is better to ask is what kind if barrel do I need to stabilze your new offering and what kind of twist is it?"... The barrel needed to stabilize the new ZA338 is a variable gain-twist, in an .008" oversize 338 bore dimension. Rifling geometry is in a twist configuration greater than that required to stabilize the projectile, and much faster than a jacketed bullet can safely be put through... in this case, a 1: 4.7" exit rate. The purpose of such a high gain function is to eliminate the engraving bands, and produce a smooth projectile shaft in .338 diameter at muzzle exit. This adds ~18% to the ballistic coefficient.
