Yes 7.62x45. NOT 7.62x39! For the CZ-52 rifle. Very hard to find ammo. Steel case 76 rounds with all the head stamps the same “AZ 79” so military surplus. I’m assuming Czech. They were loose. I boxed them up. $100 picked up in my area, Bedford. I’ll take them in my inbox with contact info wins. Don’t bump the thread. Thanks!
