Ok now this idea isn't just gently rolling around in my head but loudly rattling around. I do have a couple of extractor questions though. I am a complete noob and have one Handi with only one barrel, so I have to ask, are all the extractors the same width so you can just swap in whichever one you need? More specifically will the 30-06 extractor swap into a 223 barrel with no mods? Where do you get the new extractor, does H&R sell them or Numrich's, Brownells, etc, or do you have to "find" one? I think this will be my first big project once i get all the info, and parts together.
