[QUOTE="nralifer, post: 2525569, member: 94556"] Bullet spin does add performance to all copper bullets that petal well, primarily because the petals are sharp so they cut through the tissue, rather than simply displace it, as the bullet spins, much like a propeller. The penetration in the expanded state is much greater. Spin adds stability and overspinning monometal bullets adds to their performance on game. As long as the stability factor is between 1.5 and 2.0 you should be good. Bullets that expand down to 1700 fps impact velocity are the greatest beneficiaries of this effects because they are designed to open more reliably. [/QUOTE]
