For loading handgun in standard carbide dies, I use a VERY thin coat of pure lanolin on my brass, applied to the clean, ready-to-load brass in bulk. I simply put a tiny amount on the palms of my hands and rub it about the brass that I've put in a clean gallon plastic bag. Leave the brass in the sealed bag until you are ready to load. Your loading tool arm force is considerably reduced and your loading dies will last much longer. It is not necessary to remove the lanolin at the end of the loading process. Nor is it necessary to remove any small residue from the case mouth. Given a few hours the lanolin will evaporate away into the air.
