My opinion on that is probably the same as ronlaughlin's, behind the shoulder, 2 jugs after plywood and carpet. On the shoulder or scapula as in a high shoulder hit I'd give it another jug for full pass through scapula to scapula. On the heavy bones and joint points would be anyones guess really. That would be dependent upon angle of entry and so many other variables. Like lemoyn, I'm greedy and want pass through performance. 2 holes is always better than one. I've personally never had a bullet failure from the XTP's with either the 250gr or the 300gr. But I've never pushed them as hard as some of you guys do with inlines. I'm not in the old people club yet but at 50 I'm surely not in the young peoples class either.
