Obviously it will vary by barrel condition, but most of the Yugo models are in good shape, and do make good shooters.
All 8mm surplus ammo need to be treated as corrosive, and you need to flush the bore and bolt face with hot water soon after firing, to prevent rusting, along with a standard cleaning regimen.
There are several commercial 8mm loads that are not corrosive, and provide good potent ammo for target or hunting.
Prvi-Partizan and S&B ammo have good reloadable brass if you are so inclined.
