I've got a CZ527 in .223, and it's extremely accurate for a light weight sporter, getting under 1" at 100 consistently (some detached clover leafs), with everything from 53gr Sierra match to 60gr V-Max. American Eagles were around 1"
I use 4198 and 3031 equivalent (Oz made, by the people who make Varget).
I've shot it out to 600 yards with the full bore guys, and can hit a small dinner plate sized target every time at 600.
It's got a detachable mag, which is very very handy, but the mag is scratchy to load, which is annoying if in a hurry.
The single set trigger is pretty good used normally, and exceptional on set.
And it's chambered for the military rounds, so has a long throat and will swallow surplus happily out to a couple hundred yards before the 1:12 twist lets the long 63 gr projectiles keyhole....I like the flexibility post zombie apocalypse not to have a .223 match chamber.
