Seems if you will have more than 1 cartridge it would make sense for weight and packing to utilize an interchangeable barrel system such as the T/C Contender or Encore with sights. What do you guys think of this? I own a 44 Mag pistol and feel if I had a barrel for it I would have large game covered (as well as SD from pistol), and with a 22 barrel I could take small game all day with minimal space needed for the small cartridges, not to mention the light weight of rimfires (LR). I like this idea also because the rifle weighs less than an average rifle, and I can pack a longer barrel with the rifle being no longer overall, if not shorter. Just brainstormin' and felt it was a great idea and figured I'd pass the idea along.
