I casted these out of that 5lb lead pipe a forum member gave me. I wanted to check the hardness of them and seem to be perfect. All were shot at 50 yards into my sand bucket. I was going to test 90gr charges too but i ended up shooting them out of my kentucky into my 100 yard target. I'll need to work on new patch material for that rifle.
CVA Plainsman .50cal Flintlock, 70 3F Goex @ 50 yards.
I lost one ball as it exited my sand bucket.
Same rifle but with 80gr 3F Goex,
Shot 3 a flinch maybe?
