The idea for lubepills I got from THR.
Beeswax and white frying fat (don't know the english name) was used on the top of the bullet by the guys at my shooting club since the 1970's. As far as I know it was never used between the bullet and the powder.
The lube pills from Rifle (THR member) are made of beeswax, parafin and mutton tallow. Since sheep fat is not that easy to be had at the supermarket I opted for the proven white frying fat but had no beeswax at that time.
On a Dutch BP forum a simular topic was opened where a guy used beeswax as a filler between the powder and bullet of a 45/70 cartridge. He found it to have better (cleaner) results than any other regular filler like carton, coffee and such.
Another Durch member send me a PM with his BP lube ingredients, it included soap. He told me to use 'real' soap, the oldfashioned type, beeswax, peanut oil and Molykote (a high pressure grease). Since molykote is a petroleum based product I used white frying fat instead, 25% of each and melted / boiled it all together in a pan. Watch out with it, it will boil over like milk, keep sturring it!
I am not saying that the ingredients that I use is better than anybody elses. I don't know since this was the first time I did lubepill shooting and have no other experience with lube but the white frying grease I used to smear on top of the roundball. My lubepills beat the white frying grease though.
Check out he barrel of my Walker after 36 shots. Maybe it was the soap (Sunlight, parfumed with citronellol), maybe not but these are the freshed smelling lube pills for sure!
