I vote for pass thru ammo. My boy nailed a monster doe last year with his 12ga.[no rifle allowed] quartering away shot and he popped her good. Double lung/heart but slug lodged in far side rib/hide. I came over to Joe and asked, "success" he responds "yep". He directs me to right where he nailed her. I looked and looked and finally could detect a very faint blood spray in the snow. Luckily, she only went 30 yds into a very thick reedy, snow covered swamp[of course], never saw another trace of blood till we found her. We were lucky, many non pass-thrus end up lost deer. Double hole all the way, if possible ,is the way to go in my humble opinion.
