A paper patched bullet is a bore diameter lead slug with a patch of paper rolled onto its surface, both to reduce leading of the barrel and to impart spin from the rifleing by increasing it’s diameter to groove size. They were very popular during the black-powder cartridge era and were provided both as loaded cartridges and as components for handloading.
The most common paper patched bullets have two laps of paper, cut to length so that the ends do not overlap. They are applied damp which causes them to shrink tight when drying. No glue or adhesive is used since they are intended to seperate from the bullet upon firing.
Manufacturers of paper patched bullets usually employed young girls or women who could wrap thousands of bullets in an average work day.
