You didn't give up and thats whats important. I think at one time or another all of us have taken shot that either we shouldnt have taken or at least should have taken a little more time before taking the shot .
What Caliber did you use......what configuration on your Thompson ?
I've tracked more then a couple of deer during my hunting life. Usually we'll try and track it ourselves .......but if it gets to difficult , or we lose the blood trail....we'll hightail it back to deercamp and come back with 6 or 7 hunters and find that deer.
Enjoy your Venison.....YOU EARNED IT !!!!
