I shot 3 deer with them this year and everyone had the most devastating entrance holes I have ever seen. One deer was slightly quartering away and I got an honest to god 6" entrance hole, nearly cut the heart in half, shattered several ribs, broke the far side shoulder blade, and stuck in the ground on the other side with a complete pass through. This was a 43 yard shot with a 70lb bow and a 415 grain arrow, the hole and penetration was impressive to say the least on a 43 yard shot.

I also had probably 15+ customers come in to show us deer shot with them and I have never in my life seen entrance holes like these heads produce.
