I fired a bunch of this off in one of my old girls, had a lot of hang fires & some miss fires, even if struck several times .
Mine was single flash hole to, I reloaded some by reaming out the pocket & removing the anvil at the same time.

Even with the hang fires & crude open sights on my military carbine it shot very well, also cleaned up the bore with those steel solids, a bit of a waste of nice 160gr solids really.

On some I pulled the projectile, saved the powder, reprimed & reloaded again.

I forgot about that lovely old girl you got some time ago, it looked like it will be a beauty, can't way to see more of her .
