Locations
These vendors sell approximately 20-55 of the rare 2mm EC ammo type, refreshing their stock every 48 hours.

To gain fast, large quantities of 2mm EC ammo, one may go to Diamond City market, buy out all vendors' ammo, then wait 48 hours on any local chair (barstool, barbershop's sofa, etc.)  to replenish the vendors' ammo stock.

Please note: It is fastest to go into Home Plate to wait the 48 hours.
