Dixie Gun Works sells mutton tallow. A medium-sized tub is $3.50.
The authentic 19th century lube I use is composed of:
1 part paraffin ( I use canning paraffin sold at grocery stores)
1 part mutton tallow
1/2 part beeswax
All measure are by weight, not volume. I use a kitchen scale to measure 200/200/100 grams of ingredients then place these in a quart Mason jar.
Place the jar in three or four inches of boiling water, for a double boiler effect, which is the safest way to melt these ingredients.
When all ingredients are melted, mix thoroughly with a clean stick or disposable chopstick. Allow to solidify at room temperature. Placing it in the refrigerator to speed solidification may result in the ingredients separating.
I use Wonder Wads too, at times, but find they don't contain enough lubricant. Fouling builds up in my barrels if I use the Wonder Wads as-is.
So, I liberally soak the Wonder Wads in the above lubricant. This works great.
The "acid test" that shows you have enough lubricant with black powder comes from looking at your muzzle. If there's a noticeable ring of lubricant on your muzzle after firing a cylinderful, then you've got enough lubricant.
The Wonder Wads barely show any lubricant at the muzzle, and sometimes don't show any. That's why I augment their lubricant by soaking them.
I load a wad in each chamber, on the powder, as a separate operation. This way, if I forget to charge a chamber it's easier to remove a wad than it is a stuck lead ball. Also, trying to seat a ball against the resistance of powder and wad is more difficult and may deform the soft, lead ball.
With a well-greased wad, my revolvers display little fouling. I've amazed friends by popping off the barrel of my Colt and showing them the fouling after a cylinderful. Much of the time, it appears no more than smokeless powder generates.
As for cooking with mutton tallow, I haven't tried that. Hmmmmm ... perhaps I'll fry some fish in it sometime.
More than 30 years ago, when I was a teenager, I had a cheap, brass-framed .44 revolver. My father watched me load it at the range, noting that I smeared Crisco over the balls.
"Boy, I'd hate to get hit in the ass with a deep-fried lead ball," Dad remarked.
Me too!
