[Fallout New Vegas] How did the Mojave BOS do so well for itself that they were able to refuse using recycled Energy munitions?

If the Courier helps the BOS out enough they fill a footlocker with recycled energy munitions everyday. The BOS Mojave chapter are doing so much worse for themselves compared to the other major branches (almost no trade or manufacturing capability that we can see) and yet their Knights and Paladins scoff at the reused ammo, so how can they afford to use only fresh cells?

The Mojave branch used to be doing a lot better for themselves. Controlling Helios one and Mccaran, manufacturing their own tech, trading back and forth with other outposts along with House and possibly the NCR.  It's almost certain that they had a huge supply of all types of pre war tech including massive amounts of energy munitions. 

Although they lost almost everything during the NCR-Brotherhood War they would have taken whatever they had left to their bunker but with such low manpower and barely any land to defend their munitions are simply left sitting in a storage room. It's not like they're still at war and constantly using up their stockpile. If a trusted outsider proves themselves enough what's the harm in giving out some of their munitions so they can put it too actual use.
