Re: Penetration and wound channel depth .. graphic ..Does SteveNC's math add up ....

Think the averaging of the two (expanded diameter/as shot diameter) should predict penetration close enough for comparison.

Does seem that airguns have "grown up", there is enough power on tap to trade some penetration for expansion when hunting traditional airgun game. So far, the predator is the best expanding design but i do hope that other makers give some serious thought to making more types available (and not just cheap knock-offs of the Predator).
