Personally I'm a fixed coc blade myself, but after seeing the hole and the amount of blood loss my son-in-law got on his elk he killed in CO last year, I am rethinking. You could place your whole hand flat in the entry hole. The problem with his hit is that it was a little high and he didn't bleed outside. It took almost 3 hours to find him with practically no blood trail. When I cut into him about 5 gal of blood came rushing out of chest cavity. He also killed 2 25lb gobblers this spring with them. Tore them up! I hit 2 solid with slick tricks and didn't recover either one. Very upset.
