Hello Gray Fox,
A 222 Remington is a great choice and yes, it is deadly accurate. Before the 223 Remington was introduced, the 222 was the darling of all bench rest shooteers and many other shooters.
CZ does make several of their Model 527 rifles in 222 Remington. They also, chamber in the more popular 223 Remington Caliber.

CZ or Remington? I have had several Remingtons and I still have one in 223. I only wish I had one in a CZ. My third CZ is waiting for me in the gun shop. I have 8 more days and 10 hours before I can pick it up. I have 3 CZs now. There are 4 more in my immediate family. I already have 5 223 Remington Rifles, so I can't quite justify one in CZ, but I justified the one coming in 22 Long Rifle.
The 223 will do everything that the 222 Rem will do and a little bit more. The availability of loaded ammo and cartridge cases for reloader is a heads up thought to. I reload all of my cartridges and the 223 is at the top of the list.
If there wasn't a 223, I'd opt for the 222 or the 222 Remington Magnum, both of which have faded from the scene. I had a 222 Remington Mag and it was a tack driver too. I wore out the barrel and traded the action off.
I would vote for a CZ in 223 Remington. Of course, I don't have a vote, but I can suggest it.
