possible tumble lube?

[butchs37]

I have access to a large quantity of a product called lubra seal http://www.rhomar.com/products/lubra-seal/ msds http://www.rhomar.com/wp-content/uploads/lubra-seal_msds.pdf Its a liquid which contains molydbeum disulfide lubricant. Would this be any good for a tumble lube? It will be used with cast bullets in a 357 henry below 1400 fps and a 40 s&w semi auto.

in my experience any 'coating' with moly needs to be thick, like KG Bullet Kote. But you can try it, what's the worst that could happen? You clean some lead out of the bore? Back when I was using Bullet Kote it was on undersized boolits and it stopped my leading. Thin coatings of moly didn't help. This was when I was shooting commercial cast, now I pour my own to the proper diameter and use a proper lube.
