Locations

 * Merchants usually sell this ammo type.
 * Enclave, Brotherhood of Steel, and Brotherhood Outcasts usually use either a plasma rifle or a AER9 laser rifle and carry ammo for it.
 * Flak 'n' Shrapnel's in Rivet City is a very reliable source of this ammo. They restock a large amount every 3 days, so you can use the wait function to gain a large number of microfusion cells. This may be a bit expensive, though.
