7 years before I was born.
Surreptitiously disassembled a 20 mm round, one nightshift on the flightline. Man, that case must've held a half-pound of ball powder! Memory says a round of 20 mm HEI weighed 15-ounces.As a kid I tried to disassemble some 50 cal Aircraft rounds. Dang those were big.
THATS EXACTLY WHAT i did with my last batch!!!that Den 42 and 43 stuff makes awesome 7.65 argie brass.
I got some TZZ later stuff that weighs maybe 1.5 grain +/- apart over 500 cases.
I have about 300 of them bagged up that all weigh the same and I haven't done anything to them yet.
