Ammunition & Weapon Parts
The finest product of a 33rd-century armoury is useless if it lacks the bullets to feed it, and even the finest weapons can suffer from wear and tear eventually.
Slug Ammo: Slug-thrower ammunition is usually made out of lead or other basic metal alloys, and its exact shape and size will depend on the gun it is being purchased for. Slug ammo must be purchased for a specific type of weapon, and can only be used for that weapon - when purchasing slug ammo, make a note of what weapon it's intended for. Ammunition can be easily manufactured by any world of the relevant weapon's tech-level or higher, though any world of at least TL2 may be able to manufacture even advanced ammunition with some difficulty. Most local gunsmiths can load ammunition to any specification required by a buyer. Standard ammunition is made out of lead or basic metal alloys.
Missiles & Rockets: Some characters might have reason to pack along a man-portable rocket launcher; or have one mounted on their favourite gravcar. Heavy weapons and their ammunition are usually outlawed for civilians on most worlds; but this price is for locales where missiles can be bought. Missile weapons always take a main action to reload.
Plasma Weapons: Plasma weapons use two kinds of ammunition to operate. One is a small cannister of hyper-compressed neutral gas, usually helium. The other is a supply of power which converts this gas into plasma and projects it towards the target. Whilst their gas supply is generally already enough to last the weapon's entire lifespan, plasma weapons use a lot of power - so for all intents and purposes a plasma weapon's ammo is limited by its power supply. Power is normally supplied using type A cells fed into the weapon's attached/integral battery pack.
