RE: anti-seize
CVA - Slick breech plug and nipple grease is the best I have used, I also use the pink breech plug tape. I have use the tape with and with out adding the grease. But when I am going to be shooting a lot on the range I use both together. I would rather be safe then sorry.
I would stay away from the knight breech plug grease, I used itwhen I first started using my inline and it seized up and had to a socket wrench to remove it. One thing that I now do at the end of my shooting at the range while the barrel is still hot, is remove my breech plug and put it a cleaner.
