Hi Baxter, I'm sorry that I've never stocked 50 cal. lead balls or projectiles.
My very first muzzleloader was a J.P. Beck 50 cal. flintlock rifle in curly maple.
I absolutely loved that rifle, but had to sell it when I fell on hard times in 1995.
I swore I'd never sell anything again, and now here I am selling off things due to poor health !!!
