I had that same type of situation quite a few years ago except supposedly we had both shot at the same time. To settle the claim I looked for the exit hole because he was on one side and I was on the other side. The buck was approximatly 100 yards in front of us when we both shot. This was a real big buck chasing a doe and he didn’t care if we were there or not. The end result was that it looked like the bullet had come out on my side. I was very disappointed in the results but had to admit who shot the deer. Since that day, I always try and hunt in a secluded area with no other hunter.
