Has anyone out there built or have experience with a RIFLE chambered for 500 S&W? I am very impressed with the 500 and the 460 S&W on the X Frame revolver and think it would be a real Hoot to Shoot out of a Marlin 1895 or similar action. A short action bolt rifle would be a thought with a 16 - 18" barrel and maybe set up with a scout configuration or ghost ring sights for a super bush rifle. New England Arms makes a single shot in 500 Smith, But I just can't get into the H&R singles. Any thoughts?
