I've seen at least two members of my Bullseye team hit hard enough with a ricochet .22LR bullet fragment to draw blood. And that's with the target at 50', the steel backstop at about a 45-degree angle sloping downward some several feet behind that, and with Homasote-type panels in front of it, with only a relatively small hole behind the target. If I hadn't seen it with my own eyes I would have claimed it to be impossible.
I didn't need any more incentive to always wear my shooting glasses, but if I had, that would have done it.
