Well, I don't want to be a Debbie downer, but, getting back to the first few posts in this thread, the question "why" was asked, while many folks may have brushed it off as being answered in jest, but it was a valid question.
I can appreciate the want or need to be period correct by purist or by reenactors, especially in event demonstrations for the public, but the reality is that wasp nests doesn't work all that well as wading in smoothbore fowlers or shotguns, and even less so if used as patching for round balls in smoothbores or rifles.
There are other period correct natural resources that work better and are far less trouble to harvest, it's true that fiber and paper card wads for shotguns didn't make their appearance until later in the 1800's when shot shells were being offered for breach loading arms, however, before that smoothbores as well as M/L rifles were being loaded using other more easily gathered materials such as wads or patches being cut from thin hides, wool and vegetable fibers (Tow) were being used as wadding .
I've used them all at one time or another while attending period reenactments and events, but when I'm hunting I use contemporary materials to load my hunting arms, lubed cotton patching for my round ball rifles and lubed fiber cushion and paper card wads when building shot loads for my fowlers and M/L shotguns, because they deliver better patterns at longer ranges and greatly reduce the chances of loosing cripples to get away a die a painful and senseless death.
Just one man's opinion.
