If you mean MFCs in Dead Money, then there are some in containers. There are also a goodly number of drained MFCs, which can be recycled; the Vigilant Recycling perk is really helpful here.
The Holorifle itself will not suffice, as it does not keep the Ghost People down. You'll need to shoot them and then use a knife, spear, or bear trap fist on them to remove a limb or the head in order for them to stay dead. This applies even if you have the Bloody Mess perk, as the Holorifle does not do normal damage. It will still knock them out in one shot with the +DMG mod, and you should have enough time to run up and finish them off.
