Preparing a bucket of my fired 7.62x51 this weekend for reloading, I came across a number of IVI 69 NATO stamped brass. 99+% of the brass in that bucket came from my own stock of USGI or Commercial brass (ball, Match, LR, Federal GMM, etc.) I don’t recall having IVI brass in my shooting stash, or seeing it when I was in uniform. However, they were all from 1969, which is the right era for me. I could have picked up someone else’s brass, or been given some that I don’t remember (happening more these days).
Does anyone know if the US Army contracted 7.62 NATO from Canada during the Vietnam era?
