I've had this in storage since the 1990's. It's South Korean .30 Carbine Ball Ammo. The ammo is on 10 round stripper clips that have 2 to a pouch with a carboard separator. The stripper clips are the desirable ones that come with a slide out magazine guide. The ammo, stripper clips and bandoleer are in fantastic shape.
From a little research it looks like the PS headstamp is PMC and the rounds I pulled out where date '81.
