OK, I decided to take a swipe at paper patching, since I've tried so much other stuff. I figure it might be interesting, especially since I've been shooting mainly cast bullets for 20+ years now.
I sized down some of my cast 435 grain 45-70 slugs, figured out the length I needed to go just a hair shy of 2 full wraps, cut out some patches, made a bullet board, and used spit to moisten the patches for rolling purposes.
I'm still working on trying to keep the amount of spit and the paper stretch consistent, but I managed to get 20 halfway decent patched rounds done. It only took me 30 patches, LOL!
Anyway, I'll have to size them down a bit to fit properly, but they should work well enough for me to have a little fun with. Here they are, sitting upside down drying...
