Hiya Funked..
That stuff shoots just fine... just about finished with a 1,000 rounds of it, turned the last 250 rounds of it and my Yugo SKS over to my daughter.
I've made an interesting discovery.. the SKS's just don't give a damn what yah churn through them... as long as it's steel cased. The Yugo does not have a chomed bore, so you must without fail clean after shooting corrosive mil surp ammo... however it should be noted I played with a yugo that had the most horriffic case of corrosion I ever saw... rifle ran fine and was not much (if any) less accurate than the 'new' yugo I gave my kid. I'da thought that the eroded throat and moon cratred barrell would be problematic.. it wasn't unless we ran brass cased ammo.. then it started ripping the tulips off the cases. Seems the brass overexpands in the eroded throat and hangs up.
On the other end of the spectrum, the SKS itself; while remarkably reliable, is not much of a sharpshooters rifle.. even handloads don't do much for accuracy improvement. There are exceptions though. I have a mint 1953 Russian Tula that shoots a 3" group routinely on Mil Surp ammo*. The best the Yugo or the Norinco could do was 5" at 100 yards. The workmanship on the Russki is pretty good, the Chinaman so-so, the Yugo... well; it shoots.

Still, not bad fer a 100 dollah commie carbine.

*a 70 dollah 91/30 boltie will shoot 2" groups, my 150 dollah M39 boltie will do sub-MOA!
