Is this corrosive? Any information on this ammo would be greatly appreciated, thanks.

7.62x51 NATO? |
Lead | |

I was sorting some 7.62x51 ammo I have and am curious about the stamped marks on the bottom of the cases. All have a circle with a plus sign in the center and
have two letters and two numbers. Is the letters code for manufacture and the numbers for the year made, and is this all US surplus? Here are the codes:

FC should be Federal Cartridge Company
RA should be Remington Arms TW I can't recall oiff top of my head. LC is Lake City The (+) indicates it is loaded to NATO specs. It is all US Surplus, no US manufactured 7.62x51 ammo should be corrosive that I am aware of.

7.62x51 NATO? | ||

Ranger, there have been some NATO that was corrosive. Mostly before 1942. Some that was made during WW-II was mildly corrosive in that they had mercuric
primers. Also during WW-II and Korean War, there were some .45 ACP ammo made by Twin City that was steel cased and had mercuric primers. Nothing major, as with
all milsurps, just do a good cleaning after firing any of this ammo.

I think you mean corrosive 30-06!
Work on the new cartridge did not start until 1946 and the 51mm length .30 cal T65 did not become standardised as the 7.62mm NATO until 1954. Regards TonyE |

sscol96 wrote: In addition to being a little mixed up on when NATO was formed, you are also mixing up mercuric primers and corrosive primers. Mercuric and corrosive are two totally separate issues. The U.S. military stopped using mercuric primers around the year 1900 or so. They continued to use corrosive non-mercuric primers until the early 1950's. Mercuric primers can be non-corrosive too.
