Pluckit - Go to a hardware store or auto parts store and get a can or tube of nickle based anti sieze. This stuff works as good or better than the stuff labeled for ML use. And because it's not labeled for use in a ML breech - besides getting a lot more, it cost a whole lot less. I normally made one wrap of teflon tape and then applied this stuff and never ever had a problem. I even use it alone for nipples and flash hole liners.
