I have gotten backsplash from metal chickens at 25 meters. Most of the pieces are bases, flattened to about 1/32 inch. None of them hurt me, but it was disconcerting. I always wear eye protection, as I only have one good eye, due to a childhood accident. I definitely would not want a piece of lead in my eye. I read somewhere that it takes 350 f/s to penetrate skin, but only 150 f/s to penetrate the eye. I have never had backsplash from a spinner, though I have found fragments on the ground around them.
