Thanks for the help guys, i think PA Bow/Flinter hit the nail on the head.i guess i hadnt thought about that, and now that i do, the shot on the last deer i shot, the single lung, was a higher shot that exited a lil far back, and when i gutted that deer i remember the chest cavity was full of blood. That makes total sense. it seems i was too quick to blame the equipment and not myself. I'll look into some anatomy diagrams and work on my after the shot tactics. thanks again
