Breech Plug Grease
Found an excellent product a few days ago when i got my winchester apex.
I have been using a tube of Lubriplate No.105 Motor assembly grease.
Its white, wipes off easily, cleans off with water and keeps the plugs from freezing up. On my last outing i fired 6-7 shots and i was able to unscrew my plug with finger pressure.
For the grease users, try it out!
