12 Gauge Shells spawn in police stations, O'Leary Prison, and other police locations.
- Always spawns in a group of eight.
- Each time one is fired, they disappear - which means they cannot be refilled with any ammo box.
- In Classic, Shells were used to craft ammunition for shotguns.
- When shot out of a gun, it splits into 5 pellets.
They can most commonly be found at Police Stations.
It is possible to have infinite shells.
There is a shell-based glitch where dropping a unloaded Remington or Mossberg and reloading it will load all the shells on the player into the gun. Unloading the gun drops all the shells on the ground, but all of the shells but one are still in the inventory. This can be used to make infinite shells.
