ArmedBear (post #22): “…If you're going to shoot full-house .44 Magnum (or heavier) loads at relatively long distances, a heavy single action will be a good deal more comfortable than a modern DA revolver. I have both, and I shoot both, but when I run out of ammo with the DA, I'm usually glad. When I run out of ammo with the SA, I'm thinking, "Man, that's all?"…”
The same reason you might buy a 69' Chevelle. Not an environmentally nor an economically good decision but still a hell of a good time.
