Being nearly 70, my offhand skills have diminished somewhat, especially when I have muscle spasms at the "wrong" time. Prior to having polymyalgia rheumatica, I'd shot 2" groups offhand at 100 yards and won lots of turkey shoots, running deer, and .22LR, 50 yard metal plate turkey shoots.
I consider myself a better game/plinking shot than a target shooter. I've shot running deer at 200 yards, standing woodchucks at over 200, and crows at 150+. Two years ago, I managed a left-handed shot on a flat-out running buck at 40 yards from a tree stand, placing the bullet between and slightly behind the shoulders as it ran directly away from me. That was one of my more memorable shots, since I'd never shot a rifle left-handed.
