[QUOTE="7mmShooter, post: 1139776, member: 81795"] Do solids have a higher stability requirement than jacketed projectiles? I.e 1.5 SG? For instance Cutting Edge bullets, their .375 425gr MTH is said as needing a 7.5" twist at 2700fps for full stability, which produces just under 2.5 SG... If based on the 1.5 SG then it only needs a 9.5 twist to be fully stable at 2700fps. [/QUOTE]
