RE: Did you ever come across a wounded deer where...
My #1 situation was a "little" different. I had a deer (that I had a legal tag for) that had a lame leg (after I took him I reached down to touch it and was touching raw bone). No regrets.
I had another situation with a doe I found on the side of the road. I called the GW and he came and put her down. If I'd had a weapon.....I'd have done so right there on the spot (she'd been hit by a car).
You were the only one there. You did what you thought was right. No comments from me......except "thanks".
