Shot three more last year...
One just behind the shoulder because her leg and above was blocked by an apple tree. She ran 40 yards and dies quick...course she was about 75 pounds of doe.
The other two were shot straight up the front leg just above the halfway point on the body. I aim halfway, but most deer shot close with a gun sighted high at close range I continue to catch the edge of the shoulder blade, bottom of spine, or ribs where they are closer together. Trailing typically not required and quite seriously I lose very little meat.
Of course I am not using hypervelocity rifle rounds.
I hate trailing during gun season. I expect to trail a little with a bow...but I don't want to be stumbling around in the woods looking for deer in the gun season. I might lose one to another hunter and I know they would, of course, run downhill!
