Well, it seems I did manage to have one of these 1/4 to shots. Not really on purpose. It turned out good this time.
It was a really quiet evening and the deer heard my movements to get into draw position. So he reacted at the shot. What I thought was almost broadside turned into a 1/4 to hit in the mid front shoulder angling rearward and down. It punched through low on the opposite side near the last rib. I was shooting from a blind so I don't know how he twisted to make this happen.
I heard some bone crack, the arrow stuck though about 3" on the opposite side and hung in the animal. It broke with the scissoring action of the shoulder.
The deer ran exactly 50 paces then stopped and stood for a 10 seconds then went down in a huge puddle of blood.
I wished I could have skinned the deer and inspect the wound but time didn't allow that. You can see the entrance wound here.
