Last year while hunting antelope in Wyoming I observed 3 buck antelope fighting. All three were the same size, 12-13 inchers, and it seemed when one got the better of the other the one that was standing by would jump in and continue. It lasted long enough that I was able to sneak up on them and watched at about 100 yards. I thought they were larger than they were, but!!! Also concerning the horn sheds, I currently have 2 complete sets of shed that my son and I had found during one of the antelope hunts that we did together.
