wonderlube isn't an anti seize. Use the silver anti seize or teflon tape.

It is a breech plug and nipple grease. I also have the ANTI-SEIZE STICK from CVA. It is black and is hard to clean from the plug and the inside threads of the barrel so I don't like to use it. I also remember it didn't seem to work as well as the Traditions stuff on another rifle I tried it on when using Pyrodex Pellets.

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.

Slick 50 One Grease is all I use anymore.
