By the way, I failed to give their info. Their Ph.# 704/684-0650 and their web address is classicarms.us . ALSO, they list this ammo as N/C (noncorrosive). I believe they are slightly misinformed. This ammo is INDEED corrosive, as it is mid 1950's military production. The last case I received was March 1955. Treat after range cleanup accordingly.
