Yeah, bear in mind that this stuff is originally made as COMBAT ammo, hundreds of thousands/millions of rounds made in a production run. That being said, most of this surplus stuff shoots O.K. But you just can't expect any of this stuff to give high performance....if it does, kiss the ground you're standing on and thank the Gun Gods that you have a crate of ammo that performs in your rig. Of course depends on the rifle/shooter combination (see sidebar below), but I too have had great results with Austrian/German surplus (esp when manipulating their components). The Hirtenburger stuff (with a match bullet placed on the end, original powder charge) shot like a house on fire in my M-24. I'm almost out, so I too am gonna try some of this German surplus.
Side bar: I had norinco .223 that shot very well out of my bushmaster AR-15, but didn't out of my Colt (apparently Bushmasters have/had tighter chambers) but probably other factors involved.
