The strongest, best and most accurate is the Ruger Old Army, no contest. The Remington is potentially more accurate than the open top Colts, but some of them are amazing, but the Remington holds a slight bit more powder, and the Ruger more. Ruger, without a Wonderwad overpowder wad will hold a bit over 40 gr of fffg. The Remington about 35gr. The Colt (Uberti) about 30 gr. The Ruger is heavier than a Colt Army or Remington, as big as a Super Blackhawk or Vaquero, but is certainly far more handy than a Dragoon or Walker, by a matter of pounds, not ounces. The Ruger will also shoot all day without binding up from fouling, a Remington not more than 2 or 3 cylinders, and a Colt a little more.
