"the 6.5s may well kill better than most would imagine b/c fast ROT keeps the bullet nose fwd which ensures better straight line penetration thru vitals/POA. As a side benefit, debated often, faster ROT may add to the damage a bullet does in tissue."
P.O. Ackley claimed that the 220 swift killed all out of proportion to it's caliber, due in his opinion to the fast bullet spin (in this case from the high muzzle velocity resulting in faster bullet spin).
