I’ve been looking for some information on this 7,62x51 mm NATO cartridge I’ve had for quite some time.
According to my copy of the “The Military Cartridges Calibre 7,62x51 mm NATO - their development and variants”, by Brandt, Hamann, Kaltmann, Kiehn, (in the book its number is “III.29.55.1”) it is an experimental cartridge by Remington Arms. Solid mild steel projectile with a nickel plating. That does tell me something about it, but I would like that the very educated minds on this forum share with me their knowledge. What was the intended purpose, what firearm platform was it intended for, and how common are they?
As seen in the photograph its headstamp is RA 60 with the NATO load symbol at the 12 o’clock position.
Thank you in advance :-)
