Some time ago, there was a pile of .303 british military ball around marked FNB. It came in a metal box of 1000 rnds, packaged inside in 50 rnd paper boxes wrapped in white cord. I have a chance to pick up some of this from an acquaintance, but I have no idea of current value per box of 50. I don't mind paying market price, but I don't want to find out later that I dropped my drawers and grabbed my ankles (financially!). Any one know a fair value of this ammo?
