The following formula is from one of Paul A. Matthews’ book, How-To’s for the Black Powder Cartridge Rifle Shooter. He says it gives excellent results. Paul says “It will not melt in the sun, yet continues to give good performance when freezing temperatures are in the single digits. It is very soft and sticky and has a bad habit of sticking to your fingers instead of the bullet when you seat the bullet in the cartridge case. It also turns dark with exposure, but this in no way impairs its effectiveness. For my money, despite these few minor faults, it is one superb bullet lubricant for use in the black powder cartridge rifle.” This lubricant works great in a lubrisizer. It is not suitable for pan lubing. Probably the simplest way to make the lube is to mix an 8-ounce batch in a microwave oven.
Basic recipe:
Yellow beeswax 2 parts (ounces avdp.)
Pure neatsfoot oil 1 part (fluid ounces)
Murphy’s Oil Soap 1 part (fluid ounces)
1. Fully melt 4 ounces of beeswax in a Pyrex measuring cup.
2. Thoroughly stir in 2 fluid ounces of pure neatsfoot oil until there are no lumps. Do not use neatsfoot compound.
3. Add 2 fluid ounces of Murphy’s Oil Soap and continue to stir until all lumps are gone.
4. Pour into container and allow to harden.
5. For 8 lbs. of lubricant use 4 lbs. of beeswax, 1 qt. each of Neetsfoot oil and Murphy’s Oil Soap.
Note: You may notice that as soon as the Murphy’s Oil Soap is added, the mixture turns a light cream color. It may also boil up violently when the soap is first added. This is caused by a chemical reaction of caustic soda in the soap, an action known as saponification, which significantly raises the melting point of the mixture and gives it a smooth, soapy texture.
