Yes, though I don't think you can make one that small with alot of power. I'm not an explosives engineer though. To say nothing of what the spin will do to the jet. I can see an APDS round for it that would kick the .50's butt, and it's possible that's what it shoots for AP duties. I'm inclined to say that APDS would provide more penetration than a HEAT round.Uh, do the words "Shaped Charge" mean anything to ya?
