One of the most important concepts in air to air gunnery is “lethal bullet density” which can be improved by “harmonization”. You can either “point harmonize” which simply means the outboard guns are aligned to the aircraft centerline so that the bullets meet a point of optimum combat firing range typically 700-800 feet. This leads to a wider dispersion at the much longer ranges, or you can use pattern harmonization. Pattern harmonization was always better for the pilots with average ability to lead the target and hit it. This pattern simply means that each gun individually was adjusted in different directions so as to produce a uniform pattern of a certain diameter. You don’t get the maximum density, but you did get a better chance of a hit. It would be like using a shotgun, instead of a rifle. Keep in mind that both aircraft are moving, in different directions, up and down to left and right and including yawing and pitching. This should explain the two methods of harmonizing the onboard weapons. Even at 2000 feet, the nominal trajectories of bullets fired by guns using either of the harmonization patterns shown occupy a space approximately the same size as the aircraft carrying the guns. Obviously, there are differences between the two patterns shown above, and point harmonization is better if you're engaging at the right range and aiming well, but, regardless of the type of harmonization chosen, if you're hitting with one pair of wing guns it's not that unlikely that you're hitting with other pairs.
