I cast a .500 with pure lead for my Encore. It won't shoot at all. I decided I still want to cast so I started in my 45-70 . Still won't shoot . SO, I swaged the 45-70 down to ..452 and paper patched them. Still won't shoot. SO, I took the swaged .452 and put them in a black sabot and tried them in my muzzleloader. I get 4" @ 100 yds with a 4x shotgun scope. Good enough for Wisconsin deer for sure. How does the pure lead bullets work on deer? Never tried it.
