Fellows, I'm curious as to how you all would rate the various COMMERCIAL Czech Mausers {forget the milsurp and milsurp sporters, here}:
How about some technical details and compare/contrast the quality, functioning, feeding, anything you can from personal experiences with these rifles.
ZG47's, ZKK602, CZ550's, whatever?
Let's hear it! 
{Erik, c'mon, I know you have a ZG47...by the way, how's the project coming?}

CZ550 FS 6.5x55
Quality: overall very good. Pretty wood, barrel nicely free-floated except at steel tip.
Functioning: 100%
Feeding: From obvious Mauser lineage, it's odd that it does not feed a controlled-round, especially as the factory told 9ThreeXFifty7 that the extractor is not designed to snap onto a singly-fed cartridge. Mine strips a round from the magazine, and it goes ever so slightly under the extractor. As the bolt moves further forward, the cartridge jumps out from under the extractor, and when the cartridge enters the chamber, the extractor snaps over the rim. I’ve read of others behaving the same.
Accuracy: Fifty three-shot groups have been fired, five or ten per session. The average of each session is 1.0 inch, with the best groups in the high 0.8’s, most in the high 0.9’s, and the worst groups are 1.4 inches. By my reckoning, it is a dependable 1.4-inch hunting gun.
Scope mounts: It appears that CZ makes rings in only one height, high. My rifle has a Leupold 1-4x Vari-X II scope, which I feel is ideal for this rifle. It would look better and come to the shoulder better if it were lower.
Iron sights: Very good. The sights are easy to acquire, and provide a good sight picture. I have only shot mine at 50 yards, where I’m able to maintain one-inch groups without difficulty.
Trigger: The unset trigger breaks at 3.5 lb with considerable creep. Set, the trigger is crisp and breaks at 1.5 lb. Neither applying the safety nor working the bolt will unset the trigger, but it may be unset by pulling the trigger with the bolt open.
Take care, Tom

Oops. I now remember I promised to take some pictures.  I'll try to get my ass in gear asap.

Erik, we look forward to seeing it!
Tom, yes, as you say, the CZ550 is not really a controlled round feed. At least mine isn't. It is much more like my Rugers than like a Mauser. Even the claw-extractor Rugers tend to just push the cartridge forward, and some allow it to hop up before actually sliding under the extractor claw, actually much like the old button-ejector Rugers. My Rugers actually gain better purchase of a round than my CZ does, however.
All those with big bore CZ550's should test them to make sure the action will function as a CF action both when operated quickly and S-L-O-W-L-Y.
Overall, I'd rate the CZ550 as just about the equal of a Ruger M77. My CZ's trigger was very easy to adjust, however. And Rugers are very easy to improve. Seems like a tie...
I assume the ZG and ZKK Czechs actually ARE controlled round actions?
Maybe some others with 550's can weigh in here. The action is touted as a CF action, but in my and Tom's case, they are decidedly not.
Mine is accurate enough for me, as posted here: http://forums.nitroexpress.com/showflat....true#Post112466
I have never shot a ZKK and never seen a ZG. The ZKK602 I handled was very crudely finished and I didn't like the concept of the "Lee-Enfield-like" trigger pinned to the trigger guard. I've never read of a complaint with it tho.

zkk-601 308 Win my first rifle. It now lives in my brothers save.
Accurate, descent finishing, not allways feeding properly, very easy to shoot because of the snellar.
