14 years old, my first deer hunt. Had a Win Model 88 .308, problem with the magazine, it would fustercluck once in a while after a shot. SO I carried my Granpas old S&w model 10 .38 with me as a sidearm, "Just in case".
I was hunting a powerline, just got out of my car, got my guns, walked up over the hill, there was a little 2x2 looking tight at me about 25 yds away. I put my scope on him, squeezed the trigger, nothing happened, no shell in chamber. When I jacked the lever to chamber a round, it jammed of course. The little buck was just looking at me with wide eyed amazement. I gave up on fiddling with the rifle, unholstered the .38, took aim at where I thought the little bucks heart was.
"KABOOM!" and the thing dropped. I set the gun down and ran up to it, blood was trickling out of a clean little hole in its neck. I was so excited, I picked up the little buck, threw it in my trunk and went home to consult my hunting book on how to clean it. Next day I Had to go back for my gun I had left on a rock.
ANother occasion, hunting antelope with a good friend, he took a spill down a hill with his gun slung over his shoulder. Later in the day he gut-shot an antelope at 200 yds, his gun was later determined to be way off after his spill. It was last few minutes of the season, the wounded buck was about to cross a fence onto a private ranch, so I took a shot with my 300 wsm. The yardage was calculated with a rangefinder, almost 600 yds. I was sighted for 300, really had no idea how high to hold for that shot, so I just put it a few inches high above the back of the shoulder, dumped the buck. Luckiest shot of my life. 150 grain Nosler went clean through.
