I nodded off one afternoon while sitting on a ridge. I was awakened by crunching noise. There was a doe munching acorns like 50 yards from me, and never saw me. I took my time and shot her, and she went down, but proceeded to blat like crazy for about 30 seconds. She was laying on her side and I did not have a clear second shot due to angle etc., I started freakin out because it sounded like a child bawling. It was disturbing to me but I dealt with it.
I did not enjoy it, but it sure does make you take a little more careful aim. Now I usually shoot at the shoulder, about 4" down from the back line, even with the front legs. They usually go down like someone reached up the arse and pulled every bone out of their body. I have yet to hear one make a peep either. There doesn't seem to be much meat in that area, and it breaks the shoulders, takes out the lungs and spine all at the same time.
