From what I've read on this forum and elsewhere the CZ works real well with pointed bottleneck bullets especially in the 375. The big shells is where you can have a problem. If CZ can get this problem resolved they will have the market cornered. I expect the price will be higher.i can,t speak for the bigger calibers in the CZ 550,s, but this CZ 550 in .375 H&H mag. has never given a problem working or hitting what you aimed at if you were up to it. this target was shot in Botswana at 100 yards from a good rest, one shot by me and then one by my PH after I had sighted it in and left it cool down. my shot was at 10:30 and the PH,s was at 4:00, both shots were inside the 1-1/4" 9 ring.
They are not particular what I feed them, either. They give me 1moa @ 100. I tried 130,150 and 160 grain in the 7, 235, 270, 300 and 350 grain in the 375 and all shot great.I have 2 70s, one 375HH and one 7Rem mag both Portugal made. They both shoot 1moa @100, look and function perfectly. They have been to Africa for DG with the 375 and Texas for blackbuck with the 7. When I open the bolt and tip the muzzle down the bolt slides home slick as glass on both of them. Just lock it down and ready to go. The safeties are a little stiff but I figure that's just the 3 position mechanism.
