[QUOTE="RockyMtnMT, post: 1180432, member: 7999"] Here is some more information regarding twist. We have done all of our twist rate calculations at sea level and 59 deg F. The original post showing our initial line of bullets are calculated based on the prevailing twist offered by manufactures factory rifles. We have done quite a bit of work on faster than normal twist in many calibers and will definitely continue to. Working on the frontier of shooting is very exciting. caliber weight length recommended twist _____________________________________________ .243 80g 1.035" 1-9" .257 93g 1.069" 1-10" .264 125g 1.393" 1-8" .277 117g 1.213" 1-10" .284 133g 1.293" 1-10" .308 153g 1.244" 1-12" .308 167g 1.393" 1-12" .308 183g 1.524" 1-10" .308 215g 1.752" 1-9" .338 261g 1.793" 1-10" Steve [/QUOTE]
