I suggest abandoning lubricated wads in paper cartridges. The geometry of a cone precludes their use. They are fine when loading chambers individually at the range with loose components, but their use in a paper cartridge is neither practical or historically accurate. You will be chasing you tail attempting that.
Nitrating paper is, in my opinion, a complete waste of time. I got almost as much residue with nitrated paper than I did with regular paper. When using paper cartridges, you
WILL get more residue in the chambers as a matter of course. It is the nature of the beast. Originally paper cartridges
facilitated the loading process and eliminated all the extra cooters you needed to tote around with you. They were never marketed or quoted to be debris free or clean burning. Even users back in the mid 19th century experienced paper debris in the chambers hence the attempts to relieve it with nitrated paper.
You will still get buildup with nitrated paper at almost the same rate as non-nitrated paper. For me, it was just not worth the extra time nitrating paper for the
minimal advantage it provides - if any. It's fun to try and you can say you did it, so by all means, give it a whirl and see what happens!
What WILL make your range session more productive when shooting paper cartridges is to bring a bronze cleaning brush that will fit into the chambers easily (like a 38 caliber cleaning brush for a 44 caliber cylinder).
Every two or three cylinders you shoot, run that brush down in the chambers and capture all the paper debris that accumulates at the base of the chamber. You can shoot paper cartridges all afternoon doing that.
Here is a photo of nitrated paper cartridge debris. I was using period paper (c 1870) with a higher rag content. Theoretically this nitrated paper should have burned itself up yet it didn't. When using nitrated modern papers like coffee filter paper, hair curling paper, or cigarette rolling paper, I still have debris accumulation, not to this level of course, but still have a significant amount.
