I've gotten the protugese stuff in the past. The older stuff was good. The newer stuff is mediocre. Doesn't look as nice, less consistent velocities and generally less accurate.

I hear imi is HOT....i have some and i "heard" it is MG ammo....i do NOT put it through the m1a....i do put it through the ."fal"....so i adjust the gas...  superior rifle...  lol

 

But i did have a case head split..ill dig up a pic...i would watch imi

Not much of this is available anymore! I had a load of Malaysian that is supposed to be good. I also have some Battle packs of south african stashed.

 

 

I save it to remind me how much pressure we are dealing with ....I put it on my bench when I reload.... 

and being this wasnt a reload....even more of a reminder

Lucky with that one!

Men and Dag are my favorite.  They always go boom, accurate enough, reliable performance.  SA for me has been ok, Radway and SK is great, but have never used port.
