I usually have two or three 527s around, all in Varmint chamberings; currently own a .22 Hornet and a rare .204 Kevlar Varmint (the most accurate factory rifle I’ve owned in a long time). Not only do CZs handload okay, many will shoot factory ammo well. The Dec. issue tested a .223 V and one 40 gr. brand allegedly produced a .15” group — a very good review from a (rare) mag that doesn’t pull punches or kiss manufacturers butts.
The adjustable single-set triggers are a plus. The few possible negatives might include the “backward” safety, and the wood stocks on some might need touching up to completely free-float the barrel. I personally don’t like the Americans and their pencil barrels; only certain chamberings come with the Varmint barrel, but both H-S Precision and B&C offer stocks to fit heavier barrels if one wants to change an American to that contour later with an aftermarket tube.
Regarding handloading: the common bugaboo of detachable factory magazine length does rear its ugly head. Most CZ chambers I’ve seen are cut long enough to allow seating bullets farther out, but the mags are right at factory cartridge length. James Calhoon does make a neat magazine-replacement follower for most chamberings, that allows single-loading without jamming.
Also, CZ sometimes offers bare actions for sale, e.g there were some Hornets out there recently, and Bud’s once had some 7.62 X 39s that some built PPC repeaters on.
IMO, C-Zs are great rifles for the money.
