Lube in Old Army with Pyrodex P

[frosty]

I am currently shooting 45gr of Pyrodex p In my Old Army. What is the best choice in bullet lubricant with this propelant? I am shooting a 200gr bullet with a lubed wonder wad with decent results, but after 2-3 cylinders I get some leading in the forcing cone area...The gun is a stainless version

I always lubed mine with alox/beeswax and it seems to work. I use the Lee tub and cutter type lube kit. Seems to work. I shoot 22 grain cast bullets from a Lee mold. Round ball, I just use crisco.
