It would help if you told us what you are trying to accomplish. If you are going to be taking the revolver afield and don't want to pack along a flask, ball bag, etc, then it is a convenience to have some paper cartridges and caps in an Altoid can. It is all you need although some grease over the chamber ends would be a good idea.
The shortcoming of this set up is the possibility of some burnt paper residue in the chambers- this is because the cigarette paper is a low quality option, a better nitrated paper ought to fully consume.
The other choice is to fill and plug some brass cases - as noted- with proper powder charges, plus wads and either balls or conicals- again - all stored in an altoids can along with some caps. Balls are usually more accurate than most conicals so that would also be a very viable option, in fact, with the lubed wads (MUCH SAFER)- it is really a better option IMHO, the only advantage of the paper cartridges is speed of reloading- maybe 20 seconds- I can reload about as fast as with a Peacemaker since the spent cases on the Peacemaker don't have to be removed.
On breaking the paper case to insure ignition. This may have to do with the nipples being used but the percussion cap ought to be powerful enough to rupture a paper case. As I said I got some very thin foil and experimented with that because Sam Colt started with foil. The caps burst through the foil but the residue is ample and after about 3 rounds you cannot seat another cartridge and the conical- sticking out the end of the chamber makes it impossible for the cylinder to rotate- a big mess. Sam Colt experienced the same problem. The Colt cartridges were nitrated fish gut- as I understand matters- and they were rather dangerous- the factory blew up, killing some workers, all women incidentally as they seemed better at the work.
I have also used plain newspaper for cartridges. This paper is about three times thicker than the cigarette paper- but once again the caps burst through and ignite the charge. The problem with the newprint is there is unburnt paper fragments left in the chamber that could easily hold a spark/ember.
Which brings up a point that ought to be repeated just in case someone isn't on board. The nitrating is NOT DONE to facilitate the cap burning through the paper to ignite the charge. The nitrating is done to address the danger of an ember left in the chamber. The nitrating is intended to burn up any paper residue.
