It just that the silly arguments

On the same token, and I'm sure you were exaggerating, but I'll just point out that knives are obviously not very good ranged weapons, due to accuracy, distance, and expendability problems.

Also, it's not like most guns we're talking about here are being shot at enough distance and enough velocity without enough rifling to actually cause the bullet to tumble and explode like would be required in the wound you're describing.
