If the firing pin was going to clog up in less than 100 shots, then I should have been warned and properly equipped to deal with it. I don't see any reason you wouldn't want the modified breech plug for all loose powders. It puts the grains about a quarter inch from the primer versus close to an inch with their standard breech plug......................
Bein's you are handy, check this out.
Them photo show a plug modified in October 2010. It has been tested thoroughly in all kind of weather, and has never failed to ignite BH instantaneously. The rifle has been left loaded and dirty in the truck over night in sub-zero weather several times. This plug works.
Myself, i prefer this plug over the made for BH plug now being sold by CVA. It doesn't require a specially made drill to properly clean the flame channel. It has a longer flame channel, thus produces less pressure on the nose of the primer. To clean this plug, one simply removes the vent, and run a drill through the plug end to end. Simple, quick, and no guessing whether the carbon has been removed from the juncture of the flame channel and flash hole. When the flash hole in this plug is worn, one simply replaces the worn vent with a fresh new vent.
When your rifle returns home, you might consider using an 0-ring, or shimming the firing pin bushing out. Done correctly, this will stop blow by from getting into the firing pin channel. A metric o-ring 1mm thick with a 4.5mm ID placed in the primer pocket will make a perfect seal at the nose of the primer. Never again will your firing pin stick because of carbon leaking around the primer. Shimming out the firing pin bushing can also make for a nice tight fitting primer which will not allow carbon to leak around the nose and thus reach into the firing pin way.
