Probably best to just quote his post on another forum. He prefaces his recipe with:
"Do not use greases or oils that are petroleum-based. The older black powder manuals suggest using automotive grease over the chambers of revolvers. Don't do it. Petroleum-based greases somehow create a hard, tar-like fouling when combined with the black powder.
The proper grease or oil is animal or vegetable-based, such as Crisco, canola, beeswax, sunflower, commercial lard, mutton tallow and similar substances."
Then the meat of it:
"My own patch, wad and bullet lubricant is a 19th century recipe, found in a 1943 issue of the American Rifleman.
The recipe is:
1 part paraffin (I use canning paraffin, found in grocery stores)
1 part mutton tallow (sold by Dixie Gun Works)
1/2 part beeswax (available at hobby and hardware stores)
All measures are by weight, not volume. I use a kitchen scale to measure 200 grams of paraffin, 200 grams of mutton tallow and 100 grams of beeswax. This nearly fills a quart Mason jar.
Place the Mason jar in a pot or coffee can with about 4 inches of boiling water. This gives a double-boiler effect, which is the safest way to melt waxes and greases.
When the ingredients in the jar are thoroughly melted, stir well with a clean stick or a disposable chopstick. Remove from water and allow to cool at room temperature (trying to speed cooling by placing in the refrigerator may cause the ingredients to separate).
This creates a lubricant nearly identical to a well-known black powder lubricant sold commercially.
To use, place a small amount of the lubricant in a clean tuna or cat food can. Melt in a shallow pan of water. Drop your revolver wads or patches into the can and stir them around with a clean stick until all wads or patches are saturated. Allow to cool then snap a plastic lid (available in the pet food aisle) over the can and store in a cool, dry place. This keeps dust and crud out and retains the lubricant's natural moistness.
I don't bother to squeeze out the excess lubricant from patches or wads but use them as-is.
This is an excellent bullet lubricant for all black powder uses. I also use it for patches in my .50-caliber muzzleloading rifle, and lubricating cast bullets for my .44-40 and .45-70 rifles. I've tried it with .357 Magnum bullets at up to 1,200 feet per second and it prevents leading. I haven't tried it at a higher velocity in the .357 or other calibers, but may someday.
I like the addition of paraffin in this bullet lubricant, because it seems to stiffen the felt wad somewhat, and scrapes out fouling better.
I've used the Ox-Yoke Wonder Wads in the past and they're good, but lack enough lubricant for my likes. I soak them in the above lubricant.
With a well-lubricated wad twixt ball and powder, you can shoot all day without ever swabbing the bore."
