New to me 58 Muzzle Loader - Picked up today. Not sure what brand. All I know is, made in Italy, and a big block capital I in a square. Looks like it has never been fired. Has set triggers. Not familiar with the 58. I have 2 lbs of Elephant FFg (was free) and plenty of pure lead. Have a .575 Lee mold inbound. Guess I'll figure it out. Maybe a BP freezer deer this year! Never taken one with a ML.
Going to shoot the simple RB. Figure 80 grns of powder. Won't shoot past 50 yds in my woods. If anyone has a better accuracy load, I am all ears.
