Gander - I agree that shooting at paper doesn't make upfor shooting at the real thing, but I shot through a piece of plywood first that might represent hitting a bone of a deer. Of the 12+ slugs I have tested the Power belts performed the poorest in penetration and mass retention. The first time I shot the power belt the largestpiece I found wasno bigger than apencil eraser the second and last time a piece no larger than a dime.These tests were performed 1 year apart with different bullets from friends. I can't understand the reason that it happened but it did. I guess I will blame it on the gun.Most be shooting to fast.GoodLuck hunting JT
