With no intention of enlightening anyone, I'll throw my choice into the "database:"
I've used LEE case lube since some time in the eighties. I did use to do some case forming for AI cartridges and necking up/down - nothing radical so this has been perfectly fine for everything I've done. I ran out and bummed a partial tube from my dad some ten or so years ago, which is dated "89," l've accidentally allowed it to freeze several times out in my shop (don't do that) but it still works even if it looks nasty. I got low enough a few years ago that I asked a friend to grab me a tube as he went galavanting about the State's gun shops one weekend and still haven't needed to get into it. That was in 2018.
To put this into context, I don't do a lot of bottle-neck cases any more, and I never did "shoot in volume" using a semi-auto. I shoot mostly 30-30 and 222 now, which I lube and full-length size once when new/used brass is acquired and neck-size with a LEE Collet Die thereafter. Someone shooting several thousand 223s through an AR may not find my choice of case lube appropriate - but then I don't know for sure that it wouldn't.
I rub (finger) a LIGHT film on the NECK, then the BODY, skipping the shoulder entirely, and then, using a Q-tip, give a quick twist inside a CLEAN neck. If I can SEE the lube on the case, it's too much. It's always dry by the time I start sizing. I usually do batches of a hundred cases, down to ten or twenty. Any time I do more, like 500 or more, it's pistol cases and I lightly lube every tenth case and use a carbide die. I clean off what little lube is left on cases with denatured alcohol on a rag, but don't make a huge production of it - twist the neck in the damp rag, twist the body in the damp rag, toss the case into a bin/basket - done. I don't mess with trying to clean it off pistol cases. Sometimes, for a large batch, I just tumble them, but I HATE picking corn cob out of flash holes. I HAVE full-length-sized some nasty 7.62x51 cases, which required some extra oompf and STILL wouldn't chamber in a bolt-gun, so I ran them through a small-base sizing die too. I got a heck of a workout on that "free" brass, but never stuck one, and MANY threatened to not come out of the die. Come to think of it, the LEE Turret Press stood up to the task and I figured I'd wear it out or at least loosen it up with 500 of those cases. Sure wasn't worth it, but the point is - the lube did its job.
It's so cheap, that I can't think of anything I could make cheaper. It works well, is easy to use, does not have an offensive odor, doesn't make my fingers dry/crack, isn't messy at all. It works really well for the type and amount of sizing I do.
