Not me. The only cartridge blackpowder I did was from:

My 3rd generation 7 1/5 SAA Colt in .45 Colt
An Uberti Schofield I used to have, also in .45Colt(I "cheated some" on that one)*.

A 5 1/5 Uberti SAA in .44WCF
An Uberti 1873 carbine in .44WCF

An Original Colt Lightning carbine and an Original 1873 Winchester carbine(both not mine but from a friend) in .44WCF.

A 4 3/4 Uberti SAA in .357 Magnum(I used .38 SPL cases and 17gr Swiss #1).

A Winchester 1886 Extra Light made by Miroku in .45-70.

* the "cheating" I have done with the Schofield was using .454 round balls over 28 grs of Swiss #1. The balls were seatead over the powder about level with the top of the cases. Then I completely sealed the cases with the same stuff I use on muzzle loading revolvers. It was very accurate, and I manage to shoot all day without the revolver binding because of fouling.
