I can safely say that I've been hit it just about every extremity but one, "You came close mark!". I have suffered everything from welts, to bruises, busted open lip, to my arms looking like I had a dozen flee bites that I kept scratching. None of it was any fun by any means. Not to mention that I work in an office environment and it doesn't look all that grand to my co-workers. Unless you wrap yourself in an armor suite you're bound to get some type of battle scar. The point is to try to eliminate the severity of such things by keeping a safe distance from each other while shooting.
