Hi all,

A friend gave me a box of 30 Carbine ammunition made by a German company called Geco. The box also has a label indicating that it was imported by Century Arms. The ammunition is brass-cased FMJ and the primers have a red lacquer seal.

Is anyone familiar with this ammunition or know if it is corrosive/non-corrosive?
 
I don't know but I always assume corrosive.

Thanks, that's definitely a safe assumption.

I should have done a Google search first --- turns out there's quite a bit of info on Geco 30 Carbine ammunition:

The round looks to be pretty hot, so I may avoid it in my M1 Carbine as it has the older style flat bolt.
 
Germans have been using RWS ROSTFREI (noncorrosive) primers since 1904.

If it's earlier than that (which I rather doubt) then you could have a problem.

Thanks for the info, Smellie. I'll have to check the date codes on the headstamp when I get home, but my original thought is that this is ammunition from the 60's.
 
.30M1 Carbine ammo only came out first time in 1940.

You're safe.

LOT of European ammo is Berdan primed. I use the empties, neck 'em down with a .218 BEE seating die and seat a .223 slug, make them into little pendants.

Have fun!

That's what it's all about!

I highly doubt it's corrosive. IIRC, .30 Carbine was one of the issued rounds in WW2 that wasn't corrosively primed. I would imagine German .30 Carbine from the 60's would be similar.
 
For what little I know, the only corrosive primed M1 carbine ammo is the FAKE Lake City stuff MADE IN CHINA.
Because of the design of trhe carbine, it has always used NC primers

GECO is the German trademark for Gustav Genschow, a firm that exported a large number of Mauser Sporting rifles after WWI. They still sell ammunition under the GECO name, but their products were more made for them under contract, rather than by the GECO firm themselves.
