This ammo is really good. I bought it for my Russian AK, steel jackets kill your barrel and since this is copper jacket your barrel will thank you. Ps it shoots 1.5 on a good day in a outside range with Russian AK. With my psa AK gen 3. About 2.5 but that's with irons. My Russian. Has a 2 - 6x scope.
