[QUOTE="nicholasjohn, post: 1746966, member: 109113"] I think that a lot of things are different with rapid rotational velocities. Even with standard twist rates, ultra-light bullets sometimes come unraveled at the rapid rotation speeds that come with extreme muzzle velocities. I remember when everybody was going nuts over 40-grain bullets in the 22-250, and sometimes the thin-jacketed bullets didn't even make it to the target. With fast-twist barrels, bonding cores to jackets is probably essential. The long bearing surfaces of the heavier bullets are also a player in how they are going to behave. I've also read that high rotational velocity affects terminal performance of the bullet, but can't say that I've had any experiences to comment on. Can you comment on that ? [/QUOTE]
