I've pretty much settled on NRA formula 50-50 beeswax, alox,(tamarack). It flat out works. I use LLA for tumble lubed bullets, and on some that are designed for regular lube, (grease grooved). I bought a bottle of rooster lube, tried it, but not enough to say it works. It DOES dry non-tacky, just can't see it, nearly invisible. So I put some food coloring in it! That made the thin film visible. Only tried it on one loading for my 45-70, no leading1
Back in the day, there was this stuff called mirror lube. Not sure what the base was, but it had a pretty high content of molybdenum disulphide in it. It was a harder lube than tamarack, so no using it in cooler winter temps in the basement. At the time, I was only loading .357 and 44 mag, it worked just great. It's no longer made, but I have a few sticks left.
I'm never going to mess around with making some super formula myself. I'd be worried about not being able to repeat the results years down the road when it would be gone. Lube like tamarack will be available as long as we're able to shoot. And for sure as long as I will be alive!
