This is a tough situation for you. If you try to have him banned from the club, it may backfire on you. If you call the authorities, he may make your life a living hell. What did the guy say to you when you confronted him? Did he at least apologize? I think I would have a private club meeting. What the guy did is against the law, unless it wasn't a public road. Most states require you to be at least 100 feet from a public road to discharge a firearm. Even if it were legal, it's not right. You may want to hold off for now about calling the GW. Have a meeting and see how that goes first. Sorry for what happened. That really sucks.
