With all the Surplus 223 ammo available for about 3.50 a box I can' t see using a non reloadable steel case.I bought Lake City head stamped 223(Made by Federal) for less then 3.50 a box of 20.The cases are reloadable.If the bullets indeed are steel I know I don' t want to put it through my gun.I' m sure it would shorten the barrels life.That' s MHO anyway?
