7.62 NATO with composite case


#1

I have a 7.62 NATO with composite case

I think this cartridge was produced by Remington.
Can anyone confirm this ?

Im sorry I cant be of any help identifying the manufacturer of your cartridge, I just wanted to say I have never seen one and Im jelous that it isnt in my collection!
I recognise your user name, Maverick1112003, I think you outbid me on a 7.62x47mm dummy round on www.munitionsauktion.de a while back.
Im glad it went to a good home :)

Check this out, CSAEOD has one of these on auctionarms and shows a photo of the box as well. Hope this helps.

Until a year or two ago I had never seen one. In the last year or so, I have seen 3 for sale at cartridge shows for between $50 and $100 each. I don’t know if some were recently found or if a few good collections became available.
Is there any info on how they performed in firing tests?

I have two of these in my collection. Careful examination indicates that they have different extractor grove dimensions - is this the difference between types A and B mentioned in the Auctionarms posting? Why was there a need to experiment with the extractor grove? Did the nature of the composite case significantly affect extraction?
