Went out to the range saturday with my premade catridges and some premade powder charges. Although the cartridges did work, i did not like using them. First, it was cumbersome to get the cartridges under the loading arm. The paper kept getting in the way. When i went to spin the cylinder, paper sometimes got caught up in between the barrel and cylinder face, binding it up. The powder charges were alot easier and less agggravating, but i still didn't care for them. I had too many misfires with the cartridges and the powder charges than i would like. I am assuming because the spark from the cap didn't ignite the paper the first time or the paper didn't break open when i loading the chamber. Of course, this is just my opinion and others may have had better luck with them, but for me, i'll just stick to pouring powder and seating the ball manually.
