I suspect that today the accuracy of these commercial rifles are on a par, with ammunition that each one likes. I suspect if one were to take 100 Savage rifles, 100 Reminton, and 100 CZ rifles one would obtain similar accuracy from the group, some in each group outshooting others.
After accuracy though, one has a number of other factors which may factor in to his affinity for one or other of these manufacturer's offerings.
The CZ rifles I own have an outstanding fit and finish. As I am partial to walnut, I have walnut stocked rifles. The wood to metal fit is imeccable. The wood is very dense, doesn't take compression hickeys easily. The wrist of the rifles I have is at a perfect angle, with a smaller diameter, no nasty palm swells. The checkering is without flaw, no overruns.
The barrels are hammer forged on my centerfires, and neither of them has ever had an issue with metal fouling. This is nice, as I really don't have the patience to spend hours removing that stuff. My rimfire is magnificent.
The action is where the centerfire CZ really shines. The controlled round feeding is very positive and reliable. Ejection is consistent and due to the fixed ejector, I can either cycle the bolt quickly and cleanly eject a round, or cycle it slowly and just sort of tilt the empty a bit in the action for easy removal with my fingertips. No silly spring loaded, bolt face located, button ejector that dents the brass neck on the chamber mouth upon extraction.
The blueing is deep and rugged and no streaking or anything like that.
The triggers are unique among rifles IME. They have a set trigger feature if you like that kind of a thing, and the standard trigger is on a par with any other you can find.
The aspect of the rifles that I would change is that the safeties work backwards from most others I have known, in that one rocks them to the rear on the 527 and the 452. (Right now don't remember the 550, whether it rocks forward to fire or to the rear to fire).
The action has dovetails machined into it for a very secure mounting of optics.
Anyways, when I am ready for another bolt actioned rifle, I will buy another CZ. I'm thinking next I would like a Mannlicher in 6.5 Swede. Just magnificent rifles.
Of course none of the other rifles is a bad choice if the Savage, Remington, or FN appeals to you.
