I use Iso-Heet and 80W gear oil 10:1 for 5.56. Dual use, both from the local auto parts store. The 80W is leftover from the last transmission oil change, and the Iso-Heet can go in the gas tank this winter.
Pistol cases seem OK in the carbide resizing die, but the die likes an occasional thin film of 80W on a case.
Seriously!? This process works?
If true, I got loads of gear oil and 5 gallons of pure alcohol sitting in my garage space that I rent.
Between Hornady's Unique case lube and that I'll never run out of case lube if I lived another life time!
