Caseless ammunition refers to small arms ammunition that packages the primer, propellant and projectile together without a cartridge case. They are fired using either mechanical or electronic means to ignite the primer. This design has different characteristics compared to traditional modern metal-cased cartridges.
- Decreased Weight because of the lack of an external metal casing
- Shorter/Smaller Cartridges
- Higher Cyclic Rates
- Fragility of the ammunition; the case is formed from the primer and propellant
- Heat Sensitivity during sustained fire
- Sealing of the chamber, an issue not encountered with metal-cased cartridges during firing
