He didn't ask about penetration. He asked how they cut. What we would both like to see are some examples from actual kill shots. I can "penetrate" and pass through a deer with field tips. But that doesn't cut the mustard so to speak. Since those are "wires" and built to collapse I think Rock and I both are a little leery of just exactly how well they will perform. You need serious entrance and exit wounds to let blood poor for tracking. I can kill a deer with field tips but I would have to hoof track the deer because there would be no blood trail.
