Bull's eye and golden ring targets were relatively easy to shoot. Shell and broken blade targets were sniper targets that the country recognized as difficult.
For the shell target, the bullet needed to hit the groove in the middle of the shell, leaving a bullet hole in the shell.
The broken blade target was at least 50 meters away. A single-edged military knife was stabbed into the wooden stake with the blade facing outward. The tip of the bullet must hit the front of the military knife. Only then would the bullet that was fired at high speed instantly bend the sharp blade and pierce through the A4 white paper behind the back of the knife.
This way, there would be symmetrical bullet holes on the white paper, and the military knife wouldn't break.
The bullet had to pass through the middle of the golden ring. Even hitting the golden ring couldn't be counted as a score. Only by piercing through it could the sniping be completed.
