I am thinking about finding another 30-30 and having it re-bored to a 38-55. I have gotten some conflicting information about the difficulty of the conversion and I am curious if anyone here has done this? from what I have read, (mostly) it's a simple re-bore and re-chamber job and the action will work as-is. I have not bought a gun for the conversion yet, but I am thinking either a beat-up or rough bore Winchester 1894 or 94, or Marlin 336, or 94. Or the cheaper store-brand versions of the same. Has anyone here ever done this? what action would be best?
