Years ago I began posting a bullet, patch and wad lubricant based on a 19th century recipe.
I used more precise ingredients than the 19th century version, which simply listed tallow, paraffin and beeswax.
Without changing the ratio, I began mixing:
1 part canning paraffin.
1 part mutton tallow.
1/2 part beeswax.
All measurements are by weight, NOT volume.
The result is an exceptional black powder lubricant that was later named by others, "Gatofeo No. 1 Lubricant."
I use canning paraffin because it's pure. Who knows what lurks in old candles, especially if they're scented. Yes, paraffin is a petroleum product. Yes, petroleum greases and oils will creat a hard, tarry fouling when used with black powder. BUT canning paraffin doesn't do this. Long ago, a chemist told me that canning paraffin lacks the offending hydrocarbons.
I don't know about that, but I do know that canning paraffin (used to seal fruit preserves in jars) doesn't create a hard, tarry fouling.
Mutton tallow is needed. I've tried a variety of greases but mutton tallow is clearly superior. I've tried Crisco, and the tallow of beef, chicken, turkey, deer, pig, elk and even bear grease. Not tried moose,though. Or Dodo Bird for that matter ... might be kinda hard to get.
Mutton tallow has long been suggested for black powder lubricant, at least to the mid 1800s.
Canning paraffin is about as pure as you can get. Totally inert too.
Mix together some Gatofeo No. 1 Lubricant for yourself. Dixie Gun Works sells mutton tallow at the best price I've found. A little goes a long way.
A hard felt wad soaked in melted Gatofeo No. 1 Lube keeps fouling soft and the bore cleaner than any other lubricant I've tried.
The dry lubricant in commercial wads is the worst, in my experience. Hardly makes a dent in bore fouling.
Make up a batch of Gatofeo No. 1 Lubricant for yourself, and see if it doesn't work for you.
