I picked up a 1100 Trapmaster about a month ago. I was reloading some shells with #12 shot the other day. I want to try to use a round ball .375" / 3/8" , my question is has anyone tried using the 3/8" clay balls used for slingshots? I don't mind using lead balls but these should be lighter and a little cheaper. I just don't want to damage the barrel.
