Does anyone know if this ammo is corrosive primed? I have some I'd like to shoot through a new AR but don't want to use it if it's corrosive. This ammo dates from 1951.

Read this. Says no U.S. made 7.62NATO ammo except 1956 "International Match Ammunition" manufactured by Frankford Arsenal was ever loaded with corrosive primers. Author's name is familiar too.

Thank you Sunray, that was most helpful.

Here is another exception to noncorrosive 7.62 ammo. While this is not truly 7.62, it is .308 Winchester loaded for the ordnance depart by Western for some special match. It contains a 200 grain Sierra FMP Match bullet. It is loaded with what appears to be IMR 4064 and has a CORROSIVE and MECURIC primer. The cases are head stamped WCC 58. The cases are very thin and are not designed for use in semi auto rifles. They weigh 30 grains less than standard 7.62 cases and are excellent for use in close chambered bolt action rifles. With these thin cases, it is possible to load the .308 with 48 grains of IMR 4350 and a 180 grain match bullet. The IMR 4350 I am talking about is the old duPont IMR 4350, not the modern equivalent. It comes in twenty round white boxes.
For those reloaders not familiar with mercuric primers, they weaken the case if fired. I always unloaded and replaced the mercuric primers with nonmecuric/non corrosive primers. For many years WCC loaded their Super Match ammo with the 8 1/2 G primer (Corrosive & Mecuric) for they felt it had a slight edge over NCNM primers.
This ammo is extremely rare and is seldom encountered.
