Rock Chuck Bullet Swage (later abbreviated RCBS) is a handloading equipment manufacturer operating in Oroville, California.The company originated during the sporting ammunition shortage caused by World War II, became a widely recognized manufacturer of handloading equipment, and has subsequently been purchased by Hodgdon Powder Company.
This greatly streamlined the reloading procedure and paved the way for semi- and full-automatic firearms. [ citation needed ] However, this big leap forward came at a price: it introduced an extra component into each round – the cartridge case – which had to be removed before the gun could be reloaded.
Depending on the application, the feed system can be either single-ended (ejecting spent cases and unfired rounds) or double-ended (returning casings back to the magazine). A disadvantage of the M61 is that the bulk of the weapon, its feed system, and ammunition drum make it difficult to fit it into a densely packed airframe. [12]
With quick firing guns (those using metallic cartridge cases) the case itself is fitted with the igniting medium; in England these are called primers. For small guns the case contains a percussion primer, usually a copper cap filled with a chlorate mixture and resting against an anvil. [2] The striker of the gun strikes the cap and fires the ...
Instead of a casing, the VOG-25 is caseless ammunition, featuring its propellant in an expansion chamber at the base of the projectile, functioning more like a mortar round than conventional cased ammunition. [56] Today it is used primarily by the Russian Armed Forces in weapons such as the GP-34, BG-15 Mukha and RG-6. Several types exist but ...
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 ...
Releasing the lock and pushing the barrel down brings the cylinder up, which exposes the rear of the cylinder for reloading. In most top-break revolvers, the act of pivoting the barrel and cylinder operates an extractor that pushes the cartridges in the chambers back far enough that they will fall free, or can be removed easily.
