All 3 of my deer ive shot with powerbelts passes through the deer and dropped them. I never believed in shooting at paper and expect the same results as what the bullet would do on a deer. Ive shot a deer with a 385 grain great plains bullet, weight through one shoulder and wedged into the other. I was shocked that it didnt go through both. And we are talking a 25 yard shot! I personally like the powebelts, they done an excellent job on all the deer we've shot over the years and put them down. The only shot that didnt pass through one of our deer was my dads first ML buck, He hit it in the chest/shoulder area and it bounced around and get up its neck. And dont fault the powerbelts on that, ive had the same thing happen witha .270 on an elk. My brother shot an elk with his 270 and it was a shoulder shot, we found the bullet in the back of its eye when we were skinning it. That i believe was a 165 grain bullet. I dont see any real point in shooting at phone books, other than for fun. But its not going to give you the same results as shooting at flesh and bone.
