Spaniel is right on with his post. Taping has really been succesful for me and I do not use any grease at all + I never loosen the BP. If you gt the tape on right and snug (not tighten) the BP up against the flange in the barrel - blow back will be stopped right at the face of the BP. Gotta thank
UC for doing the art work
As he indicated wrapping the plug correctly is the key... Here is a wrapped plug and the same plug removed after 20 some shots I think..
Here is a wrapped Knight plug ready to be installed....
To me it really is import to overwrap the nose of the BP... to create the seal at the end of the barrel...
