Yes, I have been witness to others making shots on game. In fact, it happened again twice in the last 3 days. I filmed a young girl and her father on a NJ youth turkey hunt this past Saturday where she shot her first turkey, and filmed a buddy of mine taking a jake yesterday. It is great to get to share those moments, and for me what hunting is really about.
Here is a link to the youth turkey hunt thread:
