I've got an older CZ 550 9.3x62 (maybe 8-9 years old, I bought it used about 7 years ago) and it's smoother than any out of the box Ruger 77II I've handled, with the exception of the RSM's.

Mine is the FS model, with the 20.5" barrel and in its McMillan stock it runs 8lbs with a Leupold 4x in Burris rings.
