A grease gun (pneumatic) A grease gun is a common workshop and garage tool used for lubrication. 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'. The channels behind the grease nipple lead to where the lubrication is needed.
The M3 was commonly referred to as the "Grease Gun" or simply "the Greaser", owing to its visual similarity to the mechanic's tool. [13] The M3 was intended as a replacement for the Thompson, and began to enter frontline service in mid-1944. By late 1944, the M3A1 variant was introduced, which also saw use in the Korean War and later conflicts.
It was found that the only cartridge then in service suitable for use with the new lock was the .45 ACP. General Thompson envisioned a "one-man, hand-held machine gun" chambered in .45 ACP to be used as a "trench broom" for the ongoing trench warfare of World War I. [35] Oscar V.

Due to their small size and charge load, primers lack the power to shoot out the projectile by themselves, but can still put out enough energy to separate the bullet from the casing and push it partway into the barrel – a dangerous condition called a squib load. Firing a fresh cartridge behind a squib load obstructing the barrel will generate ...
Paper cartridges were often coated in beeswax, lard, or tallow, which served a number of purposes.They provided some degree of water resistance, they lubricated the paper-wrapped bullet as they were pushed down the bore, they melted upon firing to mix with the powder residue and make the resulting fouling easier to remove, and they were not as hazardous to carry and handle (especially in ...
