To gain large quantities of 2mm EC ammo fast, one may go to Diamond City market, buy out all vendors' ammo, then wait 48 hours on any local chair (bar stool, barbershop's sofa, etc.) in order to replenish the vendors' ammo stock.They will replenish their stock after 48 hours, however. The stores that sell 2mm EC rounds are sold in very low amounts along with being very expensive.They are more commonly found after level 30. 2mm EC rounds are extremely hard to find in containers at lower levels, so much so that even with investment in the Scrounger perk it is possible that even by level 25-30 the Sole Survivor might only find a single stash of these rounds.The ammo does not become available from vendors until level 28 (or possibly level 22 in some cases), increasing in quantity at levels 30 and 35. These vendors sell approximately 20-55 of the rare 2mm EC ammo type, refreshing their stock every 48 hours.

2mm EC ammo may also be found in rare loot from level 22 onwards, or found along with randomly spawned Gauss rifles. I am currently level 35 and in that time, I have found no less than FOUR legendary lever action rifles, but not a SINGLE.45-70 cartridge.The enemies that dropped the rifles had no ammo, there is no ammo in containers, nobody uses the non-legendary rifles, no vendor sells the ammo and it cannot be crafted in the ammo bench. 45 Round, Combat Rifles Lever Action Rifles Pipe Guns Pipe Revolvers Radium Rifles Submachine Guns, Gunpowder 3.

This is the only placed instance of a 2mm EC cartridge in the game.
