It is good to do a little old-fashioned Bullseye shooting just for the mental discipline. A bit of long range from time to time is fun too. Hitting a 200 meter ram is impressive, but not as difficult as those #$@@^ turkeys at 175.
With GI ball and a GI 1911, center the bottom of the blade with the top of the notch, then cover a GI E type silhouette with the blade. At 200 meters you should make the target fall about 75% of the time.
It was a good way to win a few bets and shame troops having a hard time on an M16 range back in the day.
