"Super Clean Surplus Russian 7.62x54R ammunition. Manufactured in the late 1970's to early 1980's. Features a copper washed steel case and full metal jacketed 147grn light ball steel bullet. During the 1970's this ammunition featured a painted silver tip which was transitioned out during the Late 1970's & early 1980's." This is the description, does not mention whether or not the ammo contains corrosive primers. For the price that it is listed I will likely buy it regardless, but for obvious reasons I would like to know ahead of time if it is corrosive.
