jdbe,
The trick to using the pink teflon tape is to start at the rear of the plug and wrapping only one layer of the tape in a clockwise direction with the front of plug facing you. Make sure you only overlap enough to cover the threads. Once you have the plug wrapped by keeping your tape snug, then take your fingernail and while turning the plug seat the tape down into the treads all the way up. Now take your favorite breech plug grease and cover the tape to lubricate it and slowly turn it into the breech.
I have been using the tape for over 2 years on all of my muzzleloaders (3 Whites, 2 Knights, NEF Huntsman) with breech plugs and it woks like a charm on all of them including the NEF. When removing the plug some of the tape will separate and work it's way into the rear scope base screw hole, but you can pick it out easy with a nipple pick or paper clip.
Coating the tape with a light coat of grease is the secret to making the tape work. I have been shooting 777 for over 2 years and I have never had a plug seize when using the tape coated with grease.
Another thing you can do is crack your breech plug loose right after you make your last shot at the range while the plug and barrel are still hot/warm and you should not have a problem.
This past deer season I started using Black Mag'3 Powder and can get away with using just breech plug grease without the tape.
I have modified my BP tool to make breech plug removal VERY EASY. I will post a link when I dig it up.
