I remember those days well.. I built a semiauto AK (probably the world’s first) on a Valmet receiver and it took a lot of chicanery to find a magazine’s worth of 7.62X39 to test it. I eventually found 30 very expensive CIA no-head stamp rounds and went a friend’s farm to shoot it the first time. This buddy said “can I try it?”. I said “sure” and he promptly fired all 30 rounds!
Ah well.
That reminds me of a joke: Johnny had two Reese’s cups. His friend Sam ate two. How many years until Johnny speaks to Sam again?
