[QUOTE="xsn10s, post: 2224814, member: 95344"] Hammer Bullets even says on their website that they use Litz to determine their BC's. The bearing surface you mentioned is to reduce drag on the bearing surface while in the barrel (internal ballistics). That's those wavy cuts on the side of the bullet. Hammer publishes that's on a cnc lathe, I've personally many similar on swiss machines some ten years ago. So like I said nothing wrong with Hammer Bullets. I understand their construction since I worked in the industry, albeit a different company. In any case since Litz determined Hammer's BC's I feel confident on the estimates the jbm calculator produced for me. [/QUOTE]
