I want 2 holes leaking. Lost a nice deer from a power belt, no blood trail. Obviously it must not of passed through. For me if I find a bullet in the hide on the exit side of a broadside animal, it ran out of gas. The bonded shockwave may not expand much compared to other bullets, but I have never lost an animal with them, and the blood trails are good. At full diameter.452 it's as big as an expanded .277 bullet. They work for me. The original post was asking if anyone was using them. I have confidence in bonded shockwaves.
