Ammunition box

Ammunition boxes are found in most places in the Capital Wasteland, they all contain ammo and sometimes weapons. Some can be locked and need to be picked.

These also seem to be safe containers. They do not regenerate their content after a certain period of time and you can drop anything in them.

If you have previously upgraded your Scrounger perk, you will find considerately more ammo in ammunition boxes.

Some ammunition boxes in rivet city, more specificly Flank and Shraphnels, will be locked but contain no contents.

Most ammo in ammmunition boxes are randomnizes every new game you start.

Actually there is a slight chance getting Alien Power Cell in these boxes. but even the character's luck is 10, it's probably about 1 out of 10x7 chance to even get one.
