Bought this off my friend for 30 bucks, he got it for free from a buddy. It is clean and functions. I disassembled it last night and made sure everything was lubricated. 28 gauge smoothbore. Was going to shoot it today with a small charge, the barrel seems in really good shape. What do you all recommend for a hunting charge in this gun? I was going to use it for a little squirrel/rabbit gun. My big concern is too much powder because I know this gun is from 67 and some were made with sub par metals. Any knowledge from yall would be incredibly appreciated!
