[QUOTE="Darkker, post: 1174212, member: 81406"] Correct, and as was just stated; velocity loss by twist is hooey. There is a calculator on Berger's site for their bullets, but here is universal, can look up any bullet length. [url=http://www.jbmballistics.com/cgi-bin/jbmstab-5.1.cgi]JBM - Calculations - Stability[/url] Just remember that your individual barrel plays a part in the final number. Barrel twists can vary from stated by 1/2 twist. A rough barrel won't act the same as a smooth one. [/QUOTE]
