The paper patched bullet was a common thing in those days, factory and reload. I saw a chart of the Sharps calibers and everything except the .45-70 Government had a paper patched bullet. They were used in British black powder express rifles and the .577-.450 Martini-Henry service rifle. If you go to the Shiloh board you will find a lot of discussion on paper patched bullets.

You could also buy bullets with paper patch already applied. Can you imagine sitting at a table rolling paper patches all day? A job considered suitable for women because of their small nimble hands. Hugo Borchardt designed a paper patch machine that would run 25,000 a day but I do not know if it was actually used much. It would have been expensive to set up and widows and old maids worked cheap.
