in fact, unless you find someone who is selling their own "hoarded" stuff at a gunshow, it has been MANY years since any was imported.
right up there is the non-corrosive South African stuff (berdan) you occasinally find.
otherwise, there was POF(pakistani) stuff (corrosive) and mixed headstamp stuff Sportsmans Guide had for a while.
Bottom Line, there AINT any "decent" surplus .303 around. The Wolf Gold and Prvi (all yugo) is exceptionally good stuff, but it's 75 cents a round or more.
and PS, the brass is "OK" certainly better than Sellier and Bellot (which was horrible stuff for reloading), but the Prvi/Wolf is easily as good as Winchester/Remington US brass (maybe a bit better).
