The Single Six convertible is one of the GREAT values in handguns. You will need to sight in Long Rifle or Magnum, and then see where the other caliber hits. They wont both shoot to the same point of aim. But the idea of having one revolver that shoots both cartridges is a great idea. The Long Rifle accuracy will suffer somewhat because the barrel is optimized for the larger diameter bullet of the 22 Mag, but practical accuracy with Long Rifle is still excellent. I get 2" groups, rested at 25 yards, from a 5.5" Single Six with open sights and Long Rifle.
