Bees wax, and coconut oil, IMO you have a patch lube problem. Back in the days of flint, and percussion firearms, target shooters used whale oil on their patches. But, the guys that bet their lives on being able to shoot not only several shots, but shoot them accurately as well, use some form tallow for patch lube. I know nothing about the modern craze of using coconut oil for patch lube, but I do know about bees wax. It doesn’t take very much bees wax to cause problems in patch lube. First off the bat much of the store bought bees wax comes from China, and isn’t all bees wax. We have no purity standards on bees wax, so who knows what’s in it. I used locally produced bees wax that I am quite sure was all bees wax, and even then when more that a very small amount was added,( just to give the tallow/bear oil more body) crusts would form where the ball rested on the powder.
I probably don’t know what I’m talking about, I’ve only been shooting black powder for about forty five years.
