RE: teflon tape on breech plug is a necessity
Use what works, I hear the tape helps with any blowback. Is that true or have you noticed any diffrence?

RE: teflon tape on breech plug is a necessity

It is my belief if you snug your breech plug up to the barrel flange - squeezing the teflon you will not get that blowback down the threads. I know a lot of people finger tight and even back the BP off the stop but I believe that asks for blowback to get into your threads.
If you look at the end of your BP the face of that BP should mate up with a simular flange in the barrel at the end of the threads... if you get a seal between these two faces then blowback is stopped right there.
Here is an old write up from several years agao that might explain what I am talking about...

The tape that you use will depend on how tight your breech plug is as it screws in - if it is so tight that it chews the tape up going in you will to use a thinner tape. I have found the pink tape (TC Breech Plug Tape), or pink tape from Home Depot (less expensive) works great in the Remington’s - but is too thick for the A&H's they need white.
The tape that is patted down over the face of the breech probably does one or two things... a) a lot of it is blown out the barrel with the first shot but b) some of it is blown up and into the gas seal between the breech plug and the barrel creating an even better seal.
One of the keys when tightening the breech plug is not tear or ball up the tape in the threads and when the to faces meet squeeze the tape but do not crush it or tear it.
Here is some information I wrote up along time ago - it works for me but I can not guarantee it for you so experiment a bit at a time...

It is my theory that sealing the breech plug should occur at the face of the breech plug against the rear flange of the barrel. If the blowback can be stopped where these two surfaces mate, blown back powder and more importantly the hot gases will be sealed from the threads of the breech plug. These gases and powder residue are responsible for the seizing of your breech plug. These same gases can cut your breech plug and cause a breech plug failure.
This subject came up again on another forum. This the information I posted and it WORKS, anyway on my four inlines. I really don not even worry about seized plugs - I shoot several rounds each trip to the rock pit.
The following picture shows my efforts as explained below.

This is one of those things that I have really been fortunate with. When I go to the range I shoot 30-40 shots 100 grains of loose t7 with 209 primers. I shoot 2 Remington’s and 2 A&H's. With all four of these guns I believe I have the breech plug thing whipped. I do not loosen or even fool around with the breech plug at the range. When I get home and get to it I turn it (them) out with very little pressure. I have tried several anti seize products, and anti seize with tape, even tried the finger tight thing, but have settled on just TC's tape or a comparable Teflon tape from a local building supply - one wrap.
From the two side locks that I built I think I have learned something.... I believe the face of the breech plug should mate up with the face flange of the barrel, if this mating is clean and tight, this mating should stop gasses from going back into the threads of your breech plug. I have blackened the face of my breech plugs screwed them in snuggly against the barrel flange - backed them back out and checked the black to see if contact had been made all the way around. The 2 Remington’s and one of the A&H's showed that there was good contact all the way around on the plug. One A&H seemed to have a very small non-contact spot. The next thing I do is start wrapping Teflon tape from the barrel end of the plug back to the nipple end. The key for me is that beginning wrap - when I am done wrapping the tape on the barrel end of the plug it should extend out from the plug - I then push and press the tape down on the face of the plug - insert it into the threads and I tighten it snuggly against the barrel flange - not tight - do not want to tear the Teflon, but make it snug because you need to compress the Teflon a bit. If you look down into the barrel with a barrel light you should see the Teflon all the way around the breech plug in the barrel. Your very first shot will drive that excess Teflon back up into any gaps there might be and your threads are sealed... (the Teflon might even cover the flash hole when your done wrapping) Popping one cap will take care of that.
That is my formula it has worked well for me - but every rifle is different so I can't say it will work for you all. I really believe it all comes down to how well the face of the plug and the face of the barrel mate up.
