[QUOTE="Bodywerks, post: 873821, member: 62694"] Have you even looked at a stability factor calculator? [url]http://www.bergerbullets.com/litz/TwistRuleAlt.php[/url] You really want 1.4 factor minimum. At 4000fps a 7.7 twist is fine. You'd probably get away with 8 twist, so long as 4,000 fps is your minimum. A bullet only gets more stable as it travels downrange, also, but you need that stability factor at the muzzle. [/QUOTE]
