Additionally, there is at least one known case of deliberate self-injection with a grease gun. [2]

The zero range, , is important because corrections due to elevation differences will be expressed in terms of changes to the horizontal zero range. For most rifles, is quite small. For example, the standard 7.62 mm (0.308 in) NATO bullet is fired with a muzzle velocity of 853 m/s (2800 ft/s).

The purpose of the grease gun is to apply lubricant through an aperture to a specific point, usually from a grease cartridge to a grease fitting or 'nipple'.
