I have seen so many weird recipes for lube, there doesn't appear to be much documentation on what each component will do other than tribal knowledge, as they say.
I will share my recipe in hopes that it solves someone elses problem.
1 ring of bol-wax
Now, I have heard folks pooh-pooh bol-wax as being petroleum based on causing problems all on its own, but, when used with other products, it has one value I find irresistable. Its sticky and makes the lube stick to the lube groves on bullets well enough to pan lube.
1 "bar" of crisco
I have nothing against tallow, lard, ...etc or otherwise, but, crisco is such a fine product for BP in general, I can't help put some in every recipe. It will go bad after a while on its own, but, when mixed with other ingredients and stored in the fridge, its never given me reason to worry.
1 "slab" of canning parafin/wax
Some form of wax, be it parafin or bees, is nice for firming up and raising the melting temp of your lube. Parafin/canning wax is easy to come by at most any grocery store.
1 cup of olive oil
Olive oil has 2 great properties. 1) is a lubricant and 2) it prevents the crisco from spoiling.
Now, if shooting in colder climates, I will use more olive oil and less parafin. If shooting in hotter climates, I will use less olive oil and put in more parafin. I rarely use more/less crisco or bol-wax.
This is my recipe, it works well, and I have not seen hard fouling with any of my guns.
I use the same thing with more olive oil and less parafin for putting over the loaded ball in my cap-n-ball revolvers/muzzleloaders.
