CZ 527 Carbine, 7.62x39mm

Shooting the rifle for the first time at Burro Canyon! I had 3 rounds fail to fire using some Russian ammo from 1980. Just for fun :)

You are absolutely correct. The bore diameter on the 527M is optimized for the surplus ammo as stated on their info. However some primers (not all) are found to have stronger primers some surplus ammo. I have seen this first hand at the range I attend on two occasions. **(remember, they state: "The barrel of the 7.62x39 has a .311 bore, contributing to its excellent accuracy with inexpensive surplus ammo.") Thanks for your concern on this matter & if you don't believe, watch the video again ;~)

Surplus ammo sometimes use a harder primer for use with military weapons. It is possible that the CZ rifle firing pin spring is strong enough for commercial grade ammo, however too weak for the surplus primers.

Yea I had a feeling that could be the case too.

Why are you so upset? All I said was to watch the video again if you don't believe me? I think I will be done with this enlightening and alarming behavior for childish / bully-like remarks. I hope George Colin isn't right abut you people by lecturing: “Think of how stupid the average person is, and realize half of them are stupider than that.” Good by & you have a wonderful future ahead of you ;~)
