It's funny, because I have heard no one that I can remember that was seeing penetration issues with a Rage. I've shot 4 deer with them, and had3 pass throughs(I spined one of them and still almost got a passthrough). 2 of those passthroughs were on hard quartering away shots that hit the thin part of theshoulder blade on the far sideand ribs on the close side. I've shot a LOT of mechanicals and I've never seen a large diameter head penetrate like these.
