Long time, no post.
I’ve got a few new rounds that I am having trouble. First off, bear with me as I only have a ruler and no calipers or mic with me so the measurements will be “about”
The first round I have is, for all intents and purposes, a 7.62×51 round albeit with a short projo. It has an OAL of “about” (told ya!!) 63mm. It is a FMJ spitzer type projo that is quite blunt. The projo appears to be coned into the cannelure.
Here’s the part that is throwing me. The headstamp is “R,A,43” Now unless I have forgotten all I know about cartridges (possible but I’d like to think unlikely) that would indicate manufacture by Remington Arms in 1943. Which was before the 7.62×51 was designed.
The primer is ringed in with a purple annulus.
My thoughts are that it was either a new primed empty or a new unprimed empty of an old lot that was loaded up with a different projo for testing?
So any ideas as to what it is?
