If you are going to use T7 then you need to seal the breech from the blowback. The easiets way is with teflon tape and the more common way is with BP grease. I choose to use Teflon.
If the plug siezes it normally is not a big thing... Plug the primer hoe and just drop boiling water into the bore and let it set. After a few minutes the water will dissolve the fouling and the heat will expand and crack the fouling alowing water to drop in...
Here is how I wrap my BP's...
And here is my theory... for the life of me I have not figured out why people would only run the plug up 'finger tight' when you are trying to seal the blowback in the bore. It should not be 'TIGHT' but I believe it should be snug, just enought to squash the tflon but not enoug to tear it...
It seems that all is not equal in the world of shooting a ML - this works for me but you will need to try what works best for you...
