Is Yugoslavian surplus 7.62x39mm ammo good quality?
Depends on how you define “quality”. The 70’s Yugo 123 grain stuff that Sportsmansguide has is fine, milsurp stuff. It’s brass-cased, which some folks prefer for some reason, but it’s supposed to be corrosive-primed. As long as your SKS is chrome bored and you clean after, it’s no biggy. Specs, it’s almost exactly equal to American Eagle ammo. It’s not super hot, but it’s far from being garbage. With the ammo situation the way it is, it’s about the best you’ll find within reason. Probably a good idea to stock up.
