Revolver or Rifle??
For a good quality, and accurate revolver, I would say 75 to 150 yards. Limited by the ability of the actual revolver(and shooter).
In a rifle?? Again the 44 is only limited by the firearm itself, and the shooter. 200-250 is no problen for the cartridge if it is being shot by a rifleman who knows what he is doing. Even farther in the hands of a real expert with a good heavy casy bullet, it makes a big hole. Tom.
