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/upl...-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.
