H - MAXIMUM ORDINATE (HIGHEST POINT OF TRAJECTORY)
Maximum Ordinate. This is the highest point the trajectory reaches between the muzzle of the gun and the base of the target. It always occurs at a point approximately two thirds of the distance from the gun to the target. The maximum ordinate increases as the range increases.
round takes a slightly different trajectory. This is primarily caused by the vibration of the gun. Variations in ammunition and atmospheric conditions also contribute to the different trajectories.
