In an effort to get paper cartridges workable for me at Cowboy matches, I ran a series of tests this past Fall. I was determined to make the cartridges work because I wanted to use the percussion pistols more at these matches. I often run a posse or shoot on a small one. This limits the amount of time I have (with loose powder/flask) to utilize more careful loading procedures. The gist of this test was to see how far I could go(simulate a day's Cowboy shoot) loading paper cartridges stage after stage with absolutely NO attention to any paper residue that remained after firing. In other words, keep loading the cartridges right on top of whatever residual paper/ash left in the chambers to simulate a "hurried pace"Cowboy match.
I utilized Sally brand hair curling papers that were NOT nitrated. I made up a simple powder "packet" (using most of the method described by "Cap and Ball" on his you tube video) but with no attached projectile. Reason for this is I use a variety of projectiles and this way I can use whatever I want that day. In the course of a four day (not consecutive) testing, in each case I used two pistols loaded all six chambers, and shot six "stages".
Day 1-two Uberti 51 Navies, 18 gr packet of 3F Olde Enysford, .375 round ball, SPG on top
Day 2-two Uberti 61 Navies, 18 gr packet of 3F Olde Enysford, DD's EPP-UG 36, sized .375 lubed with SPG
Day 3-two Uberti 60 Armies, 26 gr packet of 3F Olde Enysford, .454 round ball, SPG on top
Day 4-two Euroarms Rogers & Spencers, 26 gr packet of 3F Olde Enysford, wool wad soaked in SPG, .454 round ball
Remington #10 caps used throughout. To my surprise, there were no issues. I observed there was some residue remaining after firing, most of the time a small amount in each chamber, but I just kept loading right on top of it. There were no hangfires or missfires. Each round went off normally. Cleaning at the end of the day revealed a bit of extra work to remove the paper residue.
That is 288 rounds without a hitch. Did I just get lucky? I hope not as using the Sally papers without the extra effort of having to nitrate them sure saved a lot of time. I will continue this procedure for the up-coming Cowboy season and see how it goes.
