[QUOTE="sodakota, post: 2254834, member: 81002"] There’s on-line calculations for determining whether or not a bullet will be stabile, Berger has one of those sites. Once the bullet is stabile I do not see any advantage of a faster twist. There’s lots of items that affect the stabilization. Such as atmospheric press, humidity besides bullet shape and length. I have a fast twist 280AI (premium barrel) and a standard 700 in 7mm RM. One odd thing is the 7mm RM easily shoots ABLR bullets better than the 280AI. That 280AI shoots bug hole groups with many bullets though. go figure [/QUOTE]
