I intentionally shot a deer moving away from me once.

Buddy had hit the deer poorly, his gun jammed (Remington 740), and he couldn't clear it. I was on the opposite side of the draw from him so I couldn't just hand him my rifle. Deer was limping away, and he said "shoot". I told him it wouldn't be pretty, he said "shoot".


.300 Win Mag, 150gr Barnes X. Deer went down solidly. Broke the left rear hip ball, nicked the spine, broke a few ribs and ended up in the far shoulder. Retained 147 grains. His hit was better than he thought and would have killed the deer, so he tagged it.

That would be one of only a few situations where I would think a Texas heart shot would be acceptable.
