My Vanguard's the most accurate rifle I currently own, its best has been a half-inch with factory Hornady loads, have not had time to work up my own.
That said, I do prefer wood.
The thing with CZ is that the company has, in several models, held the line on encroaching plastic stocks, MIM parts, and overall quality decline in general that cheapen some other brands. Their rifles continue to offer very good value, and at decent price levels, if you like traditional materials & proven designs.
Currently doing a 9-gun CZ project, 7 of which are rifles.
The 527 .223 has a Burris Predator Quest scope on it, in CZ rings.
With the sporter-weight barrel, its best 3 shots at 100 yards was 1 9/16 inches off the bench, with two different loads.
That's not too bad with a sporter, the gun is trim, light & handy, well-built, and the set trigger is a nice bonus feature, especially for paper punching.
A varmint version should do a little better, I'd think.
Even CZ's plastic is well done, I was surprised to see the suppressor-ready poly-stocked 455 .22LR out-shoot the 527 .223 at 100 yards.
Both with & without suppressor attached.
Of the 7 rifles here, the only one that I'm not all that enthusiastic about so far (have not shot it yet, planning to take it to the range today) is the new 557. Nothing wrong with it, just a push-feed action that's replacing the older 550 Mauser actions.
One of the attractions of the CZ centerfires for me has been & remains that Mauser controlled round feed.
Anyway- point being that the CZs are good buys, and unlike some other companies, they'll even sell you spare parts like firing pins & extractors.
I'm no blind fan boy of any one company, I choose the best from several to fit specific needs & niches.
Of the 9 CZs I'm working with on this project, the two 75 9mms were bought after working with them on previous projects (as excellent no-plastic-framed examples of a quality-made defensive handgun), the 455 FS .22 LR was another test sample I bought a year or two back after trying it out, the 550 FS in .30-06 I'm keeping from this go-round, along with the poly-stocked 455 suppressed .22LR.
The little 527 in .223 is a sweetheart & I'm trying to talk myself into letting it go back when I'm done with the project.
Figured I'd end up buying at least a couple of the test samples, but can't keep 'em all.
Still undecided, but looking through the vault for something to sell to finance this one.
The 527 carbine in 7.62x39's also very tempting, but.....
