• Place an ammo drum on a vehicle
  
  
• Select it and change the ammo caliber to either rotary or heavy autocannon.
  
  
• Select the ammo type you want (unloaded, kinetic, high explosive, fragmentation, armor piercing
  or incendiary.
  
  
• use the section grid and select the drum with it. Then save it as a vehicle, use a short and easy to
  remember name, if you want to paste it in later sometime, then name it something like XML ammo drum.
  
  Now when you have it set up it's time to edit the file.

Now it's time to edit the file of your drum and make it hold whatever ammo you want.
you can find your vehicle at:

C:\Users\[User]\AppData\Roaming\Stormworks\data\vehicles
(in folders)

then search up the name of the vehicle in the vehicles folder.

Open the .xml file with notepad.

It should look something like this:


Change the property_ammo_type="8" to one of the ammo types below this image.



Then, press ctrl + S to save the file. Hop back into stormworks and reload the vehicle you just edited.
