I use the yellow teflon tape that is designed for gaslines. I wrap the plug once with a little overwrap and then lightly grease the leading edge of the plug and tape with Knight Breech Plug grease. I then screw in the plug by hand, finger snug it then back up a hair. I also loosen the plug at the range immediately following my last shot, works with both my ML' s (an Austin & Halleck 420 and a White M98). Never a seized plug, even with T7.
