I shoot paper patched bullets in my very shallow groove Schutzen. They look like this:
Yes, that's just the bullet with no powder charge.
That said, I don't think paper patching a roundball would work very well.
My reasoning here is the bullet, as you can see has a great length to it. This long length of paper seals off the high gas pressure keeping the gas from burning the paper and blowing past it.
(As we know, hot gas blowing past the patch ruins the accuracy.)
The roundball on the other hand has almost no length where it contacts the bore. This will cause even a tightly fit paper patched roundball to loose the paper to the flames.
Another obstacle to a paper patched roundball is loading.
As many have found, even a good strong tough cloth patch can be damaged during loading.
Any tear in a cloth patch will rapidly burn thru and result in poor accuracy.
Paper, especially lubricated paper has almost no strength and if the ball/paper load fits tightly as it should the paper will be ripped when it is loaded.
The weakening of a paper patch due to lubrication is the reason my paper patched bullets are not lubricated until the moment before inserting them into the barrel. I once tried lubing them right after making them. A week later when I tried to load them the paper simply ripped off leaving a bare soft lead bullet touching the bore. :cursing:
Yes, the old "cartridges" used in Military muskets were made from paper but in that application the paper was more for containing the powder in a quickly loadable cartridge and the paper served mainly to hold the ball in place, not to seal the bore.
