I've tried many types of lubricated wads
I my C&B revolvers that is
.
I found no advantages, but potential disadvantages.
MY standard loads contain 3F black powder (yup, the real stuff) & a round ball.
Top with a very small amount of generic vegetable shortening (from a long-necked condiment dispenser - $.99 at wallyworld).
Does not run out into my holsters (even in 100 degree weather-retained by surface tension).
Bore stays consistently clean, fouling is soft, accuracy & performance is maintained. Oh - it's super cheap, too.
