I have read from several seemingly reliable sources that a 50/50 mix of mutton tallow/beeswax was right up among the top of the heap of good black powder lubes, be it for shotgun wads, patched balls for a rifle or whatever. What kind of tallow do you use FlintFan. As I recall it was stated one of the primary reasons for the mutton tallow was it didn't go rancid as quickly as some other tallows more so than actual effectiveness.
