I have one. The magazine is sized for longer cartridges so it is criticized that the .458 Win Mag version will allow cartridges to shift forward under heavy recoil. That does happen but I haven't had a serious problem with it as of yet. You need to glass bed the stock. I use open sights only and the gun shoots low when drawing a fine bead. I have never been able to get any rings to hold on this rifle. It feeds nicely. The rifle is heavy and awkward but it handles heavy recoil very well. It is a nice poor boy's big and dangerous game rifle. I've tried customized Mausers, Ruger 77's and No. 1's. So far the No 1 was the most dependable but it is a single shot. But all in all the CZ is the best compromise of price and performance in a magazine .458. Unless you hunt a lot with a rifle of this size, I think it is perfectly adequate for the normal big game hunter who probably shoots it less than fifty times a year.
