Back to my original question on pg 1...why do modern muzz loaders need to pull the breech plug? Is it the fuel? The priming? Stainless steel construction?
I have several sidelock ML's of varied ages. one is 165 yrs old...never had a breechplug out yet. ???
I pull the breech plug for ease of cleaning both the barrel and the plug. I use BH209 with a CVA BH209 Breech Plug and it gets really dirty in the flash channel and flash hole. I have read the cause of the slag accumulation as being the shotgun primers. Apparently they use a large volume of some nasty stuff. After having a hang fire during a shooting session I now clean the flash channel and flash hole routinely.
