Some time ago I posted about using paper cartridges on my Pietta 1851 Navy, .36 cal. The paper got jammed between the forcing cone and the cylinder causing the gun to jam. At the time I suspected that I used too much paper so I vowed to use less paper AND to nitrate the paper. So I got some coffee filter paper and nitrated it, made cartridges using less paper and lubed the balls. No joy! I still get paper jams.
Here are pictures of the old style cartridge and the new. New style first and old style second.

I am beginning to think that it is the gun and not the cartridge but I would like any input from paper cartridge users to see if you have experienced this. I measured the gap between the cylinder and the forcing cone and it is .004" Perhaps too large allowing unburned paper to blow out there?
After reading n=Mr. Gruenns book carefully he did not give dimensions for a .36 former.
Mine tapers from 0.27
Mr. Gurnee does not give dimensions for a .36 former. His book is mostly for the .44 and packaging.
I measured my former mandrill and and here are the dimensions
. Sorry but he numbers are decimal fractions that is the best I could do.
The former tapers from 0.27" to 0.40" and the taper is 1.44" long.
My choice was nitrated coffee filter paper because It is stiff and sturdy enough that a single layer is sufficient.
The coupon for the body is in the form of a trapezoid approximately 2" wide with bullet end 1.19" long and the chamber end 1.0" long. The small end is closed with a hair curler paper disk. This may take some adjustment.
I use a heel bullet with the top edge of the tube enclosing the heel and all the paper goes into the chamber with a bit of the base driving band sheared off.
Two weights of a proper .375" heel bullet can be purchased from Old West Bullet Moulds at a reasonable price.
I am about 75 rounds into this cartridge making thing and this is what I have figured out so far.
All of this applies to a 17 grain FFFg powder charge and the Colt Cartridge Works bullet.
I have not a clue on using a ball to make the cartridge, but would suspect the ball would be glued to the paper below the widest part of the ball.
Commercial paper cartridge making ceased in about 1890 so we are reviving a skill that has been lost 130 years or so ago.
Comments and suggestions, appreciated snarky cracks will be taken with humor,
