Magical Companion Ammo (Fallout: New Vegas)

 is a miscellaneous item in Fallout: New Vegas.

About
but there are ways to obtain it if you go to the ghoul companion in his shack and reverse pickpoket a grenade or mine to him the ammo will show and you can take it
 * The Magical Companion Ammo is a special ammo type that companions with a ranged weapon use when no regular ammo is in their inventory, Magical Companion Ammo is presumably infinite and hidden. e.g. Boone has an endless amount of ammo for his hunting rifle, and as there is only his clothing in his inventory, the Magical Companion Ammo is hidden. Otherwise, the player could obtain infinite ammo.
 * If you use this ammo for Lily's Assault Carbine for instance, the ammo will not be unlimited. It will be fired like regular ammo.

Characteristics
Ammo that only companion characters carry. It can sometimes be found on their corpses and may occasionally glitch into their inventory when pickpocketed. For example, it appears in Boone's inventory when reverse pickpocketing dynamite. Cass may also drop her companion ammo to be looted if killed by the Van Graffs
