It seems like an almost endless supply. 7.62 X 39 MM, 7.62 X 54 MM, 8 X 57 MM Mauser, and several pistol calibers are all still being manufactured in corrosive form. Is there some kind of specific reason for this? I can't see it costing any less since non corrosive priming has been around since before the early 50's. You would think with the corrosive effects this ammo has if the guns that shoot it aren't properly attended to, they would shy away from it. Most all of this stuff is either Russian or Romanian-Bulgarian. I don't know of any corrosive ammo still being manufactured by the United States or Great Britain. Bill T.
