Lube No Nos
Don't use crisco. Contains salt. Go cheaper and buy unsalted vegetable shortening. Don't use bacon grease. Same as above but more so.
Unless you are really lucky, toilet bowl rings are not made of bees wax any more. Look at the box before you buy. If you find some bowl rings that have been in stock for several years they are probably bees wax. If they are, buy them. You won't find beeswax any cheaper.
Any "organic" fat, olive oil, vegetable shortening, unsalted lard, mutton tallow, home rendered deer tallow etc will protect the metal of your gun and do no harm to the wood. Mineral oil, vaseline, Ballistol etc also work well.
I am not a fan of overball lubes. I buy sheet felt from <http://www.durofelt.com/>, punch wads with an 11mm punch from Harbor Freight (six in a pack for around $5) 7/16 also works well. Soak them in melted bullet lube(1 part pariffin, 1 part mutton tallow and 1/2 part beeswax). Put these between powder and bullet. Enough lube melts out on firing to give some blown around lube and the felt disc seals the chamber and prevents chain fires. They also act as a scraper and keep the barrel fairly clean. Much cleaner to deal with than loose lube..
