[QUOTE="MontanaRifleman, post: 843539, member: 11717"] Here is Berger's twist calculator. An SF of 1.1 or better should give you basic paper punching stability An SF of 1.5 will give you terminal stability inside 500 yds Beyond 500 yds you can get by with less than 1.5 [URL]http://www.bergerbullets.com/litz/TwistRuleAltWP.php[/URL] [/QUOTE]
