I've taken many handgun courses where we trained to shoot from prone. We had mock up simulations of shooting under a car, behind a wheel, behind a curb,etc. In a SD situation, it can be a great defenseable position, same with a rifle of course. It is LOUD when you shoot close to the ground thoughm but for Sd, I think it should be mastered as well. I have only shot a few game animals from prone in the field, as said, it is difficult to find the right set up. I've shot creedmoor too, and in a SD situation, say you got knocked down,etc, your legs make a fair bullet sponge, it can keep you in the fight. Get mad, stay mad, finish it.
