romanian ammo (i also have some of that ) is not as hot as the turk fodder you should be o.k with that ,but remember to clean real good when done cos the mil-surp ammo more often than not uses berdan primers which are corrosive so a good clean with water to nuetralize the residue is in order,.
yes, commercial ammo is purposely downloaded for just this kind of situation it will be o.k to shoot in your gew88 (lower pressure than european ammo and the use of a .321 dia pill),
like i mentioned it;s a lawyer thing.
have a great day and shoot forward
