Bought my first muzzleloader on GB last week, and it arrived today. It was advertised as a .40 cal, ~1850 target rifle, likely for Picket bullets. Lock works only intermittently, and there are some other issues, but now that I have it, some of the parts seem to not quite match (perhaps later modifications or add-on’s?) though overall, I’m pretty pleased with it as a project.
However, anyone know why my bore is hexagonal? Or more about what I might actually have here? Is that just how rifling looked back in the day?
