Every winter I wonder about this. Should I worry about 22.'s ricocheting off the frozen ground? I know they do. I've seen two holes in the snow, one where the bullet went in, and one where it came out. I haven't shot my 22.'s with the ground frozen since. I've never seen anything in the gun safety books about this, but it seems like a legitimate concern. Is there something I don't know? Do bouncing bullets generally have such a low velocity that it isn't something you need to worry about? Is my squirrel hunting over until next spring?
