For pistol cartridges it's not much different than normal reloading,
with these rules:
- (as Hawg said) Completely full case to base+ of bullet, vibrated down to max natural compaction*
- I suggest 3F powder
-
Soft bullet allot 30:1 or even plain lead
-
Soft bullet lube, not regular commercial lube unless specifically-made for BP**
* vibrate the powder to lowest point to determine what "full case to bullet base" really means. Seat bullet firmly to powder, but
do not use the bullet to compress the powder. You will deform the bullet.
** BP lubes are 2:1 crisco/beewax,
DGL,
SPG, etc.
Expect more performance, recoil, and muzzleflash than you'd guess

Clean up w/ hot water and a drop or two of dishwashing soap. Dry/oil thoroughly,
