I got a bunch of Turk 8mm ammo (which is dirt cheap) a couple month ago to feed my new M48 based rifle. Shot about 150-200 rounds in three range sessions, without checking the rounds for cracked cases, etc. Amazingly, there were no problems at all (well, maybe some cases were just a little harder to extract then others), even though quite a lot of the extracted brass had split throats.
Then, I carefully sorted through the remaining 500 rounds or so, and it turned out almost one case in 6 already had split throat! I mean big cracks, sometimes open, bullets moving in the case and sometimes seated very deep! Unbelievable how this kind of ammo worked with no problems... Now I am wondering if some "fliers" I experienced were caused by the bad rounds (otherwise, I was getting some 100 yards 5 shot groups under 2.5" from cold barrel). Next time I go to a range, I'm shooting only rounds that checked out OK, for groups at least! Maybe shoot up some bad stuff at the end of the session, just for fast offhand blasting?
Now, I just got another lot of the same stuff, which turned out to be from 1949 (the first lot was from 1946).
I checked several clips at random, and there were no cracks at all! But, all brass was discolored at the throat in the same way, like it was heated to anneal it before seating the bullets. Looks like somewhere between 1946 and 1949 the Turks finally figured out what was going on and started annealing their brass (at the throat only), which took care of the problem. Makes sense, no?
