This is the biggest revolver North American Arms ever made. It is the 450 Magnum Express (unofficially known as the Eagle). Most guns also came with a 45 Winchester Magnum cylinder as well. Since the 45 Win Mag is still somewhat available, this is what most people shoot. At $20 a round, the 450 Mag Express is reserved for special occasions. A single round is fired at the beginning. These rounds are 40yrs old, but still pack a punch and kick a little more than the modern 45 Win Mag rounds.
