Shot placement is always king.
I shot a deer with a Swhacker Broadhead once. It was a 20 yard chip shot out of a treestand. The Broadhead failed miserably. I was using my 200lb crossbow so energy and penetration is generally not an issue. When the arrow struck the deer the aluminum body of the Broadhead collapsed jamming one blade I the partially deployed position. You can see where the blade is jammed in the second picture. The other blade was free to deploy normally. Being jammed in this position stopped the arrow in its tracks. The hit was a good hit and the only thing that was cut was a rib. The arrow never reached the vitals.
I know all this because the deer was recovered as my hunting partner had shot the buck before it got to me. His shot was fatal but the deer was still moving and covering ground so I shot as insurance to put the deer down. The arrow literally bounced off the deer. I was amazed to see the hit and watch the deer take a couple of steps and see the arrow fall out.
