I have no doubt that there is occasionally a
factory CZ with a problem - heck my Win 70 Stainless Classic safety could not engage from the factory, I had to adjust the camming surface for it to work! So, I guess it happens with all makers. But it really seems that most every time a CZ issue is documented to its logical end, it involves a rechambering job: .458 Win to .458 Lott were great candidates before the factory produced the Lott, and the usual issue was half-witted "gunsmiths" pushing a reamer through the chamber (easy) without adjusting the feed ramps to the longer cartridge - duh !?!?!? Or, it involves a re-barreling job, especially in the hard to feed .500 Jeffery with rebated rim or the monster .505 Gibbs, etc. Clear back to the early 1900's British gun makers had to design special magazines to feed the .500 in a single stack column, and wider magazines with deeper feed ramps to contain the .505, for them to work reliably. What makes current folks believe that this ought to be any different today !?!?!?
There is nothing suspect with the feeding of a $1,000
factory CZ and every last one of them is function tested and test fired at the factory, and delivered with its target. Yes, the feeding ramps may be rough from machining marks and the action may be tight, but ready to shoot they are, and not for $3,000 but for $1,000...
Here is the dirty secret, and no I am not denigrating the Win 70: what folks interpret as a smooth action in the Win 70 is actually a loose action. For sure it does not need a break-in period, the tolerances are much bigger. In truth, CZ actions do require a break in period, because this is because they are machined much tighter, with lower tolerances than the Winchester. I see this as a plus, not a minus...
No contest on the lack of elemental deburring and polishing of machine cuts on the CZ, and I just cannot fathom why they continue to shoot themselves in the foot with that, but do not be confused by the internet bashing. As I am fond of saying, there are pretty darn good reasons why Rigby of London used the CZ 550 actions to build their $15,000 rifles for decades when the Mauser magnum was out of production...
As to the CZ 550 going away, I hate to say that this would not surprise me. Objectively, they are worth a heck of a lot more what they are sold for, the company must not make much money on them. I for one would wish that they cleaned up their act (and their actions) and sold a fully polished rifle for a little more money rather than discontinue a rough rifle. Oh well, what can I say, some marketing genius probably knows better
