I've got a 457 Pro Varmint and a T1X as well.
I put the 457 Pro Varmint together as a rifle to shoot NRL base class because I thought I would be able to shoot each match in both classes.
I didn't care about the scores in base class as much as just wanting to shoot more.
Later, I picked up a Tikka that a guy on the Hide had, which had some extra magazines, a Timney trigger, and a few other goodies.
I've added the vertical grip and wider forend to the Tikka.
Both rifles shoot very well. I'm not crazy about the stock on the Tikka, but with the add ons as well as a recoil pad to keep the stock from sliding around on my shoulder. I'm also not crazy about the Pro Varmint stock on the CZ. I added Victor Co. cheek riser to get a better cheek weld, as well as adding flush cups and a rail for an Atlas.
I wouldn't hesitate to shoot a match with either rifle.
