Back in the day when I used to shoot timed, situational woodswalks, we often encountered ambushes which required speed loading. We carried paper cartridges and wrapped balls in a cartridge box. The balls had a single, loose, overhand knot that released upon firing. We called them "Jaeger balls." They were lubed with bear oil. The paper cartridges contained only powder. In use, you tore the paper and dumped it down the barrel, followed by the tied ball. For safety, we always primed from the horn. In other scenarios, we used conventional patched ball loads.
