I spent a day fartin around with the 88, finally starting to land hits - took out vDallas and 3 others attacking a V-base, its best used on a fighter if the fighter is diving straight in on the base, take his range and minus 200 yards or depending his speed - could be up to 600 yards for a lead shot.
Not sure exactly, but he was 5.5k away - I set the range for 4.9k and took a wing off.
