For years now I have been wrapping my Knight breech plugs with Teflon tape versus using any type of grease. I have always used the normal White plumbers tape to complete the job. And it really has been a good experience for me.
So after wrapping this is what a completed project would look like
Well, this summer when working with technician doing a safety check on a commercial kitchen hood, I noticed that he was using a different Teflon than I had seen before. I asked him about the tape and it was his feeling it was a stronger tape and tended to seal much better than the normal white Teflon. With that small bit of information I thought it might be something I would like to try with my muzzleloaders.
So for the last few months I have been using this tape and 'for me' it certainly has proved to be a better sealing possibly stronger tape. The way I do this project the BP is completely cleaned and brushed with a wire brush to remove all foreign materials. Then with the BP inserted in the ratchet and socket I start a wrap around the nose with the tape extending over the nose. Actually I wrap the nose with two wraps then start down the BP to the ends of the treads. Cut the tape and then turn the BP in your thumb and forefinger to press the tape down in the threads. This tightens the tape to the body of the BP.
When the BP is wrapped, cut, and pressure rolled in your fingers the last step is to tap the taped that was extending above the nose down onto the nose. The two wraps over the nose will most always provide a near positive seal at the nose when the BP is tighten snugly up against the shelf in the breech.
It does take some practice to get the good wrap but once you have mastered it - it becomes very simple.
