Components influenced by caliber in Ballistic Efficiency are muzzle velocity, trajectory, vitality, and vary. Muzzle velocity is the pace at which the bullet leaves the barrel. Trajectory, or the bullet’s path, is usually flatter for quicker bullets. Vitality, or stopping energy, is the drive of the bullet upon impression. Vary is the gap the bullet can journey successfully.
