Recently ordered a brand new out-of-the-box CZ 550 Safari Mag in 458 Win Mag as an additional brown bear back up rifle (We don't have any local gun shops up here that sell CZ's so I couldn't handle one first). Overall quality was initially questionable. When I attempted to cycle the first 3 rounds from magazine (with new ammo) the rifle jammed 2 out of 3 times. I attempted again...and again, jams. Eight out of 10 rounds jammed! The rounds that did cycle, albeit roughly, were ejected with damage to case and/or bullet. Needless to say it's been sent back to the factory. But as I explained to the CZUSA gunsmith, one jam in 500 is too much for those of us who actually carry these weapons as DG rifles. Additionally, the floorplate would not release because of a poorly fit stock that wedged against the plate. Amazing that this rifle passed inspection. As soon as I get it back I'm getting rid of it. I've already replaced it with a Win. M70 Super Express - what I should've done in the first place. No more CZ for me. Anybody else face this sort of fiasco with CZ's?
