Cleaning & lightly coating Traditions bolt/plunger actions is a MUST. Where did you find any literature on lithium being a good anti-seize??

The best two hunting store-bought breechplug greases are CVA Breechplug & Nipple Grease along with Tetra Grease. Lather ALL plug threads - hand-tighten - remove & watch as some grease stays in the bore threads - re-lather - reapply at hand-tighten. After every 8-10 shots, use a socket/wrench & socket extention if-need-be for best/easiest results... check to see if the plug is loose - then re-hand-tighten. Once you are completely done shooting & the barrel is still warm, loosen the plug two complete turns until you get home for cleaning.
