Buckshot
Took 9 pellets of #1 buckshot in a hunting accident a few years ago. The sensation was like standing next to a fire lit with gas. Just a rush of air around me. It didn't hurt till later although I lost some movement in my arm for a few minutes. Got hit in both arms, both legs, my back, crotch and butt. Hit in the side with most travelling around, a range of about 20 yards. Still have one in my left leg and feel it every once in a while. I walked quite a way out of the woods when it happened and didn't feel any pain for an hour or so. Had one removed from my back against my spine, one fell out of my butt on it's own. Besides my leg, the rest were through and through.
