Can't believe the story as told. I shot several 'dillos when I was a kid. I was using .22 shorts because they were cheaper than longs. I killed rabbits, squirrels, skunks, 'dillos, 'possums, and most other Texas wildlife that was legal to shoot (and maybe a few that weren't). I've shot bb, .22, .177 and .22 (5mm) pellet rifles and several bb and pellet pistols. I've had a bb or two bounce back and hit me, but never hard enough to cause concern.
I've got a small 'T' shaped scar on my forehead from the case of a .22 bullet. I was stupid enough to lay some .22 longs on the ground and shoot them with a bb gun. One case came back and hit me in the forehead. Sure did bleed! Until I got to a mirror, I thought I was probably gonna die!! I often wonder how some kids live to be grownups; including me.
