In my late teens, always carried a 9mm Hi Power when hunting. Used it when I came across an armadillo, raccoon, even dropped a squirrel once with it.
One day, a few weeks before deer season, our private range was quite busy with gents checking the zero on their scoped rifles. Gent joins the firing line on our 200 yd range with a 44 mag revolver. He will set his target at around 30 yds, fire a few rounds, move it to 50, fire a few more shots and then set his target at 100 yds. I had put my scope on his targets to see how he was doing shooting off what I recall was a sandbag on one of our benches. Pretty darn good groups on his target. I chat with him and he tells me where he deer hunts area is heavily brushed so a fifty yard shot on a deer was typical....that it'd been years since he'd used a rifle or shotgun for deer hunting, that his pistol did just fine. He will ask me to spot for him while he tried his hand at shooting at a spot on the 200 yd berm while standing upright. He did lean against one of the firing line roof supports to steady himself. Spot on the berm was about 8" in diameter. While none of his 5 shots hit the spot, all hit two or so inches from it. I was impressed. By the way, his pistol had open sights, no scope.
