I know that every mosin is just a little different, but generally speaking how accurate are the elevation adjustments on the rear sight of the 91/30 specifically? So I.e. if you set them to 1000m and you were somehow able to see your target without a scope, would the bullet impact anywhere near where you were aiming? I don't even really get why the russians made it adjustable to out past say 600 meters, never mind 2000, did they really expect soldiers to be using iron sights out to 2000m?
