You can buy excellent pre-mixed lubes for just a few $$. I use White Label 2500 a lot, but for your application the old NRA 50-50 formula will do nicely.

A couple of solid sticks will cost you less than a cup of Starbucks.
Learn to pan lube. Or just soften the stuff in hot water and fill your lube grooves with your fingers.
Paraffin wax is a poor bullet lube, although it IS used to harden up mixtures which are too soft. Forget it for now.
Pulling a bore snake through will not tell you whether your bore is leaded. Nor will a quick eyeball. You will need a bore brush wrapped with fine steel wool.
Has that gun ever been fired with jacketed bullets? If so, the deposited copper must be completely removed. Copper will grab lead like nobody's business. Until that bore is squeaky clean, free of all metal fouling, you are just chasing your tail.
