Thanks Britsmoothy, the load info I got with it said .480 ball and 50gr 3f. I've had the same thought about range, and I can keep the range pretty close behind the house, like 30 feet close.
A wad punch came in the mail today, I'm going to try some thin cereal box cardboard for wads. What do you think about a felt lube wad between the powder and shot wads?
Also, the bore measures .498", I'm thinking about going closer to .470 ball with .018" patching. I prefer thicker patch, smaller ball for easy loading. My 20guage trade gun shoots very well like that
