2mm Electromagnetic Cartridge (Fallout 4)

The 2mm electromagnetic cartridge is a type of ammunition for use in weapons in Fallout 4.

Characteristics
Much like in Fallout 2, 2mm EC rounds are used by the incredibly powerful Gauss rifle. These rounds are exceptionally rare and expensive and also take the most resources to craft.

Weapons using this ammunition

 * Gauss rifle
 * The Last Minute

Locations

 * A single cartridge can be found on a counter in the armory of The Prydwen, sitting on a tray with other ammunition. This is the only placed instance of the object in the game.
 * 2mm EC ammo may also be found in rare loot from level 22 onwards, or found along with randomly spawned Gauss rifles.
 * These vendors sell approximately 20-55 of the rare 2mm EC ammo type, refreshing their stock every 48 hours. The ammo does not become available from vendors until level 28 (or possibly level 22 in some cases), increasing in quantity at levels 30 and 35.
