Ah Ha
A question I can answer !!! Okay !!! I don't have a clue
Never shot conicals although another shooting friend has sent me some, haven't shot 'em to date. But, it's really simple. Take the cylinder out of the gun (or not). With a stick that fits the chamber, first measure the conical from base to tip. Mark stick with pencil (or Pen).
Pour some poudre into the chamber until it reaches the bottom of the stick when the stick is held with the mark on the lip of the chamber. Then add just a little more so you can compress it.
Now . . . . and this as really really important . . . . the actual amount of poudre is completely immaterial. Seriously. So long as you get a tad of compression, your gold. Oh, I almost forgot. I suggest 3F.
See !! There it is. Super simple. Shouldn't take more-n-hour to figure out. Easy Peasy.
