Sorry... I didn't recognize the obvious snail when looking at the picture.
Hawg is right about thickening up the Crisco for field carry (I use 2-3 parts
Crisco to 1 part beeswax) , but straight Crisco's fine just to get you started
at the range.
Use
either 2 or 3F of either Black or Pyrodex depending on what you can get.
At Minieball loads of 60gr or less it's fine.
(I'd definitely use black if you have access)
