The answer it to keep folks like Mike Orlen busy converting ole' two pipers into user friendly configuration. Another option is to buy generic BLNE from Birmingham for not a lot more and have field ready gun from the start. I recommend 12ga because for upland use where Pb allowed one can use readily available Winchester Featherlites or equivalent Fiocchi loads available at many better sporting goods stores. In EU these are referred to as "trainer loads".
