Arthur, I had that exact scenario happen. It was a 250 pound field dressed 9 pointer I shot back in 2002. The shot was about 25 yards give or take. He wasnt broadside when I shot, more of a quartering away and turned right as I released. My arrow hit about 2inches left of where the tail is conected to the body. My arrow weight was 380grains, I was shooting a NAP Spitfire with a 1 1/2 inch cutting diameter. The arrow impacted heavy leg bone and I think pelvic bone, but burried to the nock. After recovering the deer a meer 30 yards later I found that the broadhead had cut the femoral artery and had penetrated over two feet and the broadhead stopped smack in the middle of the chest cavity taking out liver and lung. Granted I wasnt shooting the almighty 400+ grain arrow but I think my setup did alright for itself.
