I just bought a new CZ 527 carbine in a 7.62x39 this AM off of GunBrokers. It is really fascinating reading on the internet about all of the ammo, primers, cases and bullets that may or may not work in this rifle. Because I bought it just for the pure hell of it, I am planning on trying all sorts of stuff to satisfy my curiosity about this little round and rifle. I�ll certainly pass on my findings�CP.
