If it is him, he lived for a while and returned to his bedding area where you shot him. Is that possible? Also, if it is him, a description again of the shot and the actual impact etc...if you find your broadhead will be a learning tool. Interesting and there is two sides to look at, 1. I hope it's not him and the possibility of yours being alive and 2. It is him and you have some, although sad, closure.

I'll watch for updates.
