I have a 20 gauge North Star West trade gun that waksupi built. I have only loaded it with shot to use as a shotgun. My grandson was here this week and wanted to shoot a musket with the ball load. Since I don’t have any of the military muskets I told him we would try the trade gun with a ball load. The only balls I had were .600 diameter and with the thinnest patches I had we couldn’t start the ball so we loaded the bare ball with a wad on top to keep it in place. My question to those that have a 20 gauge NSW gun what diameter balls do you use and what patch thickness.
Thanks
