Caseless Ammunition
Caseless ammunition has existed for over 200 years, originating back on Earth during the late 1980's or early 1990's, but didn't reach widespread usage until man began to seriously explore and colonize space. Caseless ammunition is simply a projectile enclosed by or attached to a plastic explosive compound. Modern compounds require electricity applied at very specific settings in order to cause detonation, which makes them very safe and practically impossible to detonate by accident. The compound detonates with almost four times the force of gunpowder, which further reduces the weight and space taken up by a round.
Modern caseless ammunition can be fired in a total vacuum, needing no oxygen source to detonate. As such, it can be fired in almost any environment, including underwater. The outside is coated in a polymer that burns up with the propellant when detonated. The propellant is 99.12% efficient, which means that weapons have very little residue, and since it is made from stable chemicals, the propellant allows exotic materials to be used in weapons which act as proof from the elements in any environment that man occupies.
Projectiles are usually made from a solid material and are intended to strike the target at a high velocity, although most are engineered to be relatively soft to prevent hull breaches on board spacecraft.
