Well for me it's an affordable alternative to heavy shot shells. I can kill 30 turkeys to the 10 I could get with the Hevi-13 for the same price. Penetration? So what? Dead is dead given 40 yards and under. And it shoots better..... No brainer to me.
It all makes the world go round.
Dead is dead.....don't see any reason to shoot anything but XR's
