Any of those you listed are better than no ammo at all. Trying to find reloading components can be hit or miss and primers are particularly expensive.Recently I've seen a batch of Turkish ammo on bandos, yugoslavian 8mm, and Romanian brass ammo all for around 60 cents per round.
I'm inclined to buy the turkish stuff because I've shot it before. Any thoughts on what is commonly available?
I've shot all those you list, except the only Romanian ammo I've shot was steel case. They all go "bang" pretty reliably. None of them group all that well; 3-4 MOA is about the best I can do with milsurp ammo. Some people report cracked necks with Turk; the only year I have had a problem with is 1947, and just with a small percentage of those.
