20 packs of 70rd ea of 1986 7.62x25 Yugo surplus ammo produced by PPU. This ammo is corrosive, berdan primed with brass cases and copper-jacketed bullets (no steel anywhere). This is the highest quality surplus ammo in that caliber, not some 1950's cracked neck stuff you can find these days. The only downside it has hardened primers for use with subguns, and may result in occasional light primer strikes. Firing second time on such rounds solves the problem. Hammer spring upgrade also does the trick.
