No, Match ammo was the first too not use corrosive primer. The Match and NM ammo were loaded on separate production lines. Where did you find 1952 Match ammo? The Nationals were suspended after WWII and they didn't resume again until after Korea ended... I'm only aware of a few Divisional/Interservice Matches until they resumed again at Camp Perry.

There is no LC 52 M72 MATCH.

.30 cal MATCH first made it's debut at Camp Perry in 1957 as T291. It was standardized in late 1958 as M72. After the matches were restarted, and prior to 1957, selected lots of M2 Ball were used at Perry.

You are right........

Sorry I have LC 52 carbine in a can next to LC 63 M72 Match.

How about the LC 63 Match: is that corrosive.

Thank you Garden Valley

All T291 and M72 MATCH is non-corrosive.

A word about your LC 52 .30 Carbine ammo. If you do not know with absolute certainty where your ammo came from you may not want to shoot it. All U.S. GI .30 Carbine ammo is non-corrosive. Some thirty or so years ago the Chinese manufactured a quantity of .30 Carbine ammo and used the LC 52 headstamp to deliberately deceive buyers. The headstamp appears to be a U.S. GI headstamp but it is just a clever copy and the ammo is corrosive primed.

Thanks from 3Gunnah and jaholder

A quick way to tell if you have the corrosive Chinese LC 52 ammo is to pull apart a couple rounds if they are berdan primed they are corrosive. Ask me how I know.

The ChiCom LC-52 corrosive can be identified by the primer, it is a gold color. USGI LC-52 Carbine ammo used a silver colored non-corrosive primer. The head stamp is a little different, but the best way to tell which is which is the color of primer. The ChiCom ammo shows up at gun shows now and then.

Not to be argumentative, but I do not believe it reliable to view the color of the primer as determining with certainty whether or not it is corrosive.

Point taken, and of course you are right. The color of a primer is not a guarantee, but it is an indicator. If I was contemplating buying carbine ammo with a gold primer I would pass on it based on the primer color and head stamp. If I had possession of some carbine ammo, and if in doubt, I would do a controlled bright nail test to make certain one way or the other, can't do that across a gun show table or a forum ad.

Yep!

I pulled apart 2000 rounds of this stuff for the bullets. Not only is it corrosive I know of a couple of KB's from using this stuff, including a registered M2. Corrosive ammo in the short stroke gas system like the carbine is bad juju as there's no way to clean without busting the staking around the gas piston nut.

The dead giveaway on this stuff is it's packed in cheap grey cardboard boxes that look like they sat waterlogged for awhile then dried. The boxes are also stamped 7.62 instead of .30 caliber carbine.

Just my humble opinion: I don't think they copied the LC 52 headstamp to fool American shooters, I think they simply reverse engineered .30 carbine from captured Korean War ammo, likely for use in captured carbines used in Southeast Asia, right down to the headstamp.
