Appreciate all of the replies guys.
The lube I ended up going with is equal parts beeswax/paraffin/vaseline with about 3-4 tablespoons of STP oil treatment.
I went to the range Thursday and put about 70 .44 specials and about 40 full throttle .44 magnum loads through it and had only the faintest streaks of lead in the bore and accuracy was consistent. Very minimal lead fouling. Almost non-existent. I was really pleased with how it performed. I doubt I'll have many range sessions where I shoot more than that.
The only knock I have is that it is a bit soft and sticky. I may add a little more paraffin next time to harden it up a bit.
