I guess since it says "Match" on the box, it fooled people into forgetting that a flying copper and lead projectile moving about ~2600 FPS doesn't kill, easily, living things. Also, if you shoot, say a 40MM cannon gun fired by say, a gunship, it will kill a deer too. But nowhere in the manual, does it say its intended for deer. I think we should gel test that 40MM round, see if it passes the FBI protocol for killing deer. I just made that up, that protocol doesnt exist for cannons, or rifles, or anything else except handguns, actually.
But seriously, its all just for laughs. Lets just leave it at that "let people take deer with whatever they want".
