[QUOTE="Guest, post: 30367"] The bullet looses rpm much slower than fps. At long range the bullet has lost a lot of forward speed but is spinning almost as fast as when it left the barrel. A 3000 fps 1/10 twist bullet will be a 1/5 twist down range when it drops to 1500 fps. I think that when a fragmenting bullet hits an animal the spinning of the bullet will send pieces of the bullet flying. A faster spinning bullet will make more internal mess than a slower spin.
