Armor-piercing (AP): A hard bullet made from steel or tungsten alloys in a pointed shape typically covered by a thin layer of lead and or a copper or brass jacket. The lead and jacket are intended to prevent barrel wear from the hard-core materials. AP bullets are sometimes less effective on unarmored targets than FMJ bullets are.
An example of a machine gun with an optional belt drum magazine, containing a starter tab and 50-round length coil of ammunition belt, is the MG 42 (shortened from German: Maschinengewehr 42, or "machine gun 42"), a 7.92×57mm Mauser general-purpose machine gun designed in Nazi Germany and used extensively by the Wehrmacht and the Waffen-SS ...
Cartridge: The assembly consisting of a bullet, gunpowder, shell casing, and primer. When counting, it is referred to as a "round". Caseless ammunition: A type of small arms ammunition that eliminates the cartridge case that typically holds the primer, propellant, and projectile together as a unit. Casket magazine: A quad stack box magazine.
Semi-rimmed cases are less common than the other types. [4] The .38 Super, a higher pressure loading of the old .38 ACP case, is notorious for being less accurate than rimless cases, and so most modern .38 Super handguns are chambered so that the cartridge headspaces off the case mouth, like a rimless case. If the chamber is cut shallow, so the ...
Handloading ammunition avoids the labor costs of commercial production lines, reducing the expenditure to only the cost of purchasing components and equipment.Reloading may not be cost effective for occasional shooters, as it takes time to recoup the cost of needed equipment, but those who shoot more frequently will see cost-savings over time, as the brass cartridge cases and shotgun shell ...
The first references to the possible use of polymers in the manufacture of casings come from the early 1950s. One of the earliest is the patent filed by Jack W. Roske in 1950 [1] and the idea was to use a metal cup joined with a polymer shell "that will be converted to gas during the firing phase to assist in propelling the projectile and thereby permit reduction in the use of the propelling ...

A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters.
