I have had this happen to me a couple of times, once when i was a kid, shot a nice buck in the next, did not drop it, tracked it for a quarter of a mile and it ran into a drive hunt where they finished it off. i was outnumbered 15 to 1. happened again later in life, was hunting alone, wounded a deer, found it about 200 yards away and had three hunters (yea right) walk up to me and claim the deer. i have also finished off a few deer for others over the years and gave them to the person that first shot it. my feelings on this, even tho i was slightly pissed at the time, is it is only an animal, not worth getting shot over.
