Anyone who does not think a deer will stop after being hit, has not shot many deer. Especially when hit in the liver or gut they will
often stop. It rarely happens but I have seen them stop with the arrow sticking out both sides. I believe this to be an exception, but as I said it can happen.
I learned a hard lesson one time. I was hunting in a thick deep hollow on a particularly dark day. There was legal time left but when a rutting buck came following a doe, making out detail (hair, muscle crease, etc.) on the buck was difficult. In the excitement of the moment my emotions shorted out what little reasoning I might possess. He was only a short twenty five yards away (measured) and in the open, I thought I could
easily make the shot. NOT! I hit him to far back. I eventually found him but lost the meat, lesson learned.
It was a twenty yard shot and I could see the deer well but just no color.
I am not an officer on the ethics police squad so I say this with no malice, just for what its worth. If you can't see color, you can't see detail, without detail it is very difficult to focus on a point of impact or a "spot" if you will. Certainly a person can and will be successful on making the occasion kill under these conditions. However eventually the laws of chance and circumstance will catch up to you and the result will be a bad hit. I learned my lesson and have not repeated that careless error. If my mistake will help someone else avoid one, then all of my "hot air" (and poor judgement) will not have been in vain. [&:]
Good luck.
