I have to completely agree with ampahunter! I took a doe on Tues. morning. Got a complete pass thru on a 26 yard quartering away shot. Broke the front shoulder on its exit and left a hole the size of a silver dollar. The entrance hole was a pinky finger too small for a fist ( not that I actually tried, but I'm just saying......). The grizztricks are what broad heads are suppose to be....A++ from me!
