I wish S&W would come out with a revolving rifle like Rossi Circuit Judge using their X-frame. A 16.5 or a 18.5 inch barrel in S&W 460 or S&W 500. Myself I would like to see it in a 357 Max.. It would be a great brush rifle.
Now that Remington seems to be hell bent on destroying Marlin I would love to see either S&W or Ruger step up and make a decent lever action in some exciting new cartridge. Big Horn Armory is on the right path but a big name company could really step up the game and start making them in bulk at a more affordable price. A .460 or .500 would make a stellar pump or lever action.
