I just picked up some surplus Egyptian 8mm Mauser ammo. It is 1970's production, brass cased, corrosive and non reloadable. It came in a box of 50rounds, at a price of $15/box. I decided to buy some to try in my son's M24/47. Has anyone tried this ammo? Does any one know if it is heavy ball (196~198gr) or light ball (154gr)? Any informaton would be appreciated. Thanks.
