- 3 to 9 casings can be found on the dead body of an enemy that was wielding a cowboy repeater or a .357 magnum revolver at the time of their death.
- When you fire a weapon chambered in the .357 round, there is a 30% chance you'll get a casing and a 15% you'll get a casing if you're using the JFP round.
- You'll get 25 .357 casings if you buy a .357 magnum case box.
- Occasionally some traveling merchants will "sell" .357 casings (among many other calibers), but they will always be for free. Likewise, if you try and sell casings to a merchant, you will not yield any money.
