The oil soap caused me some Pyrodex, 777 problems, I think. Part proceedure on my part I am sure, but the soap was harder to get out of the crevaces in the breech plug between shots, I attributed to hang,miss fires. Oil soap went away so did problem.
Not good to use the oil soap any stronger than around 10-15% of the swabbing concoction. I only use the oil soap with roundball patching sometimes & that mix is...
6 parts water/alcohol
1 part oil (cutting or Ballistol)
1 part Murphy's Oil Soap.
I think that works-out to approximently 12-1/2% oil soap.
