If anyone would like to try .58 minies out of their ML, let me know. I have six different moulds / styles that vary in weight from 275 to 608 grains and all are cast in 99.98 pure lead. If you know your bore diameter, I can also size them from .575 to .580. I can also provide load data for each projectile to get you in the ball park. I can also provide lube, which is a non-petroleum, beeswax-based lube that I make myself.
I shoot all out of 1-48, 1-66 and 1-72 twist barrel.
Thanks,
Macbeau
