David, antler eater pretty well summed it up. The buck I killed this year with the snypers was a classic text book shot, the head slid in between the ribs going in and coming out. I hit nothing but hide, and soft tissue, and a rock on the far side of the deer. The entrance wound was larger than the exit wound( I latter found that this is common with the snypers, and is a good thing). The exit wound was still impressive, and was the actual cutting diameter of the head, 1 3/8". the only thing I can tell you is to pick up a pack and try them. If you like a mechanical that penitrates like a fixed blade head, comes from the pack sharp, and is plenty strong, you will like the snypers. They don't cut as big a hole as some other mechanicals, but You won't have to worry about penitration with them if you shoot a well tuned setup with the proper amount of KE.
