When I first started casting, I used NRA 50/50 lube for everything with reasonably good results. When I first started using black-powder (BP), it was a disaster. Very hard fouling and poor accuracy. Straight Lee Liquid Alox was worse. It appears that petroleum products do not play well with BP.
I bought some SPG lube and it worked well with BP, with two exceptions. The first problem was cost. I have since found a recipe that gives a very good imitation of SPG (roughly equal parts beeswax, lanolin, and canola oil), so cost is not as important now. It even looks and smells the same as SPG. The other problem is its low melting point. I still have that problem. When I go to my monthly CAS shoot any more, I have to chill the cartridges in the refrigerator for a day and keep them in an insulated cooler until they are shot. Before I started doing that, I often had misfires or hangfires on really hot days.
Does anyone have any experience with a BP compatible lube that has a higher melting point than SPG? I am thinking that anything with a petroleum base will not work, but I am no expert.
