Mine is probably less gooey as I make it using beeswax. It has a better consistency in the heat compared to bore butter or Crisco.
I use water pump grease to seal the chambers. Best thing I found to use, been using it for almost 20 years now. A big tub of this stuff goes a long way.
Doesn’t run much in warm weather. Gets hard in below freezing weather. In fact it’s punched holes in paper targets at 25 yards, when it’s super cold outside!
Here are some black powder versions of popular firearms. Before you ask you can't swap cylinders.

Is this stuff water soluble? Where can you buy it?
TIA,
I’m not really sure, if it’s water soluble or not. It was used in old vehicles. I was given a huge can of this stuff years ago, from a old guy that’s been shooting blackpowder revolvers for years. He told me it was the best stuff He’d ever used, and I have to agree. Works great, and I doubt I’ll ever use that entire can of grease in my lifetime, a little goes a long way. I just looked on a few websites, and it’s still available for sale.
Any chance you could post up a picture of the can?
