So, instead of Buy-ing ammo, would you simply buy gunpowder? and carry it with you? Would this be more economical, weight-wise, if on the run? Of course, I'd plan on having 10-20 30 round clips, some loaded some not, before I'd start re-loading my own bullets on the run.
How much gunpowder can one carry in a 6000 cu in backpack? a 7000 cu in backpack?
