Years ago I went pheasant hunting with my son and one of his friends. When we got to the hunting area, I discovered that the only shotshells that I had were a box of Trap 7 1/2 Handicap loads. A couple of hours into the hunt, we jumped a 2 point buck. The buck did a couple of jumps and fell down. I then saw a fresh wound on his hip and it looked like his leg as broken.
I had a deer tag in my pocket, so I switched my O/U to the top full choke barrel, slowly walked up to about 10' from him and put 1 1/8 ounces of #7 1/2 shot into his forehead, put my deer tag on him, and that ended my deer hunting for that year.
What if it were a bighorn sheep?
I've told this story before ... The year before I shot my last Mt Unlimited ram, I came up on 2 legal rams a little over 10 yards from me. I had killed a full curl ram the year before, so I just picked up a small rock and threw it under hand and hit one of the rams.
Both of the rams ran up the hill and I heard a shot. Seconds later both rams ran down to me. One ram ran out into an avalanche chute to me left, and the other ram ran to my right. He had been gut shot and he was dragging his smsll intestines like a rope. I followed him to the next chute and finished him.
I then went back and found the guide and his hunter who had wounded the ram, and took them to their ram. I then helped them pack the meat over the mountain back to their camp. The outfitter invited me to stay for dinner and gave me his biggest t-bone steak, and he made sure that my golden retriever got plenty of bones.
I ate my ram tag that year, but I went back to that mountain the next year and shot the other ram.
