SA (Small Arms) Ammunition and Manufacturing process
Small Arms Ammunition refers to a complete round/cartridge or its components, including bullets or
projectiles, cartridge cases, primers/caps and propellants that are used in small arms.
Small Arms Ammunition is primarily cartridge-based. The main function of a cartridge case is to expand
and seal the chamber against rearward escape of gases when a cartridge is fired. The shape of case
can be straight (pistols), bottlenecked (rifles), or tapered. Shotshell tubes can be made of brass, plastic,
or paper. With caseless ammunition, the bullet is embedded in a block of propellant rather than fitted
into a cartridge case. The absence of a case makes it 50% lighter than normal rounds for the same
terminal ballistics, but it is not widely used.
Bullets can be either of lead or metal jacketed. Bullet jackets are generally made from gilded metal or
copper-coated steel. Military ammunition, whether rifle or pistol, is full metal-jacketed. High-velocity
rifle ammunition used for hunting, and high-velocity revolver and pistol ammunition cartridges are
partial metal-jacketed: the metal jacket is open at the tip of the bullet to expose the lead core (soft point
or hollow point), causing the bullet to mushroom upon impact. Blank cartridges are sealed with paper
disks instead of bullets, or have a crimped neck.
