Since you asked... Here is a picture of me after being hit with a very large bullet fragment at my local club.
Why did this happen? Because, two yokels decided that it would be a good idea to setup a steel dueling tree at the 7-yard line in the lane next to me. I was just about to go ask them to put the tree further downrange when, Whack! I got stung by a huge lead and copper bee.
Boy, was I glad that I had my ANSI Z87.1 Spec Oakleys on that day!
Did you have a conversation with them about this.
