The wax toilet rings have many chemicals in them along with beeswax. That is why they don't rot.

If you want a good lube, that will handle up to 2,000fps in .40 through 50 cal, try 65% Beeswax/35% Vaseline- or 60/40 - works for me, for smokeless and BP loads and keeps BP fouling soft for repeated shots no wiping - as long as the grooves are for BP- IE: square and hold enough. With smokeless, normal smokeless bullets work.

Beeswax from a bee keeper cannot be beaten.

I have tried parafin - it is not in the same Province let alone ball park when used as the wax stiffening agent in a bullet lube mix.
