My new CZ 452 ZKM wmr and Winchester Full Metal Jackets

[MUNGAM]

I just picked up my new CZ 452 ZKM WMR and the only ammo I could pick up for it at the store I got it that night before going out was Winchesters mag. full metal jackets... The CZ would not cycle them properly and would miss fire 2 in 5 bullets. The three that would fire out of the five went exactly where I wanted to place them, amazing gun. I will to pick up several different kinds of ammo to see how they all shoot but now I have to wait till next weekend. I Hope its not the CZ but the ammo.

Is yours the 'American'? I'm looking for a full stock 22 WMR. Can't seem to find one

Nope, its the LUX.

Have a gunsmith check for a rough, short, or tight chamber, or a slight burr at the chamber mouth.

There is a known issue with 452 magnum variants and misfeeding magazines go to Rimfire Central under CZ forum and check out the stickies there is one there I believe that deals with home remedies for the mags. Never mind here is the link to what I speak of:
