I bought a H&A action and am starting to build my underhammer. I have a Green mountain .50 cal barrel and started working on installing the breechplug. My first question is the plug that came with the action screws right into the breech with only finger pressure and no resistance, just like a nut and bolt. Is this normal or should I be concerned about loose fit? My next question is about fitting the plug. I filed off the first couple threads to get past the part of the breech that is not bottom tapped. I worked the plug face flat with a file and checked frequently by marking with a sharpie and bottoming it. Once I had a pretty complete circle I honed the face with a fine stone. Now on last check I have a circle with a couple small, less than 1/16" breaks. The face is very flat and I have been tightening with an offset 4" screwdriver. Should I crush fit with more pressure now? which brings up the next question... How tight is tight? any fraction of a turn past making contact? or amount of force on a certain size wrench. This is my first time installing a breech plug, so I just want to make sure I get it right. :idunno:
