I've been hearing a lot about different lubes. Imperial Wax Lube being the best hands down say many. Some use Imperial, some Dillon spray lube, and some like Vaseline.
I'm still very, very, new to this, but I started resizing with what I had around, and moly-grease worked well enough -- then a huge
brainstorm: why not the lube-wax I use (very successfully) for my black powder revolver..???
I have tons of it around, so why not?
Anyway, I tried it and it worked really well, much smoother than the moly-grease or I would guess Vaseline. My thought is it will work as well as Imperial since it seems to be made of nearly the same kind of ingredients.
I was totally surprised at how smooth it ran though the Lee resizing die. I thought I'd throw this out for anyone wanting to give it a whirl.
Tony Sopranno's Re-Sizing Wax Lube
15% canning paraffin wax
35% beeswax
50% any kind of veggie-oil or animal fat you can scrape up
and a smidgen of Murphy's Oil Soap
(I've used just about anything and everything for the fat/oil component from neatsfoot oil, to mink oil, to hamburger fat drippings, bacon grease, and olive oil.... but just plain old Crisco is good 'cause is easier to collect from the supermarket shelf.)
...Point being if it's veggie oil or animal fat based it makes little or no difference.
After the two waxes are all melted down add the 50% oil-fat part and then a small tad of Murphy's Oil Soap as an emulsifier. I usually stop when the Murphy's smell is evident in the mix. This is the point where the emulsifier properties really take hold, and it makes a nice composite waxy-soap-oil mix. And nothing will ever rust or corrode when it comes into contact with this stuff.
As it cools down it looks just like saddle soap but it smells pretty close to Murphy's Oil Soap -- and it's great stuff! I have a bunch of it here (poured into little breath-mint cans) for my BP gun so trying it out made lots of sense. It's probably a hassle to mix-up but if you have this stuff around, or feel experimental, give it a try. I doubt you'll be dissatisfied.
If I'm wrong please let me know, but for me this stuff seemed as smooth as "grease through a goose."
