The BEST 8mm is the Yugo M75 sniper ammo. Wideners and Classic Arms have it. If you look around diligently you might find some Yugo standard ball from the 1970s. It is darn near as good as the sniper and sells out fast.
There are a couple cases of Romanian 150gr on Gunbroker, steel case stuff but still surefire. 1950s Yugo would be last, in my opinion. I still get duds even with an extra power firing pin spring.
