1) I don't think that any fruit has a consistency that will yield meaningful results for anything except over-penetrating a grapefruit.
2)Over-penetration is almost entirely a phantom issue. Look at the number of rounds fired that completely miss the intended target in defensive situations. That singular, theoretical round that happens to hit AND happens to exit the other side is very near the bottom of a very long list of things to worry about in a defensive firearms situation.
Still happily answering to the call-sign Peetza.
You do not HAVE a soul. You ARE a soul. You HAVE a body.
He is no fool who gives what he can not keep to gain what he can not lose.
