The Savage MK II BV is average- I own one, but in the case of mine, price is about all it has going for it. It is a decent rifle, but mine is rough. I wish I could boast groups similar to what has been posted, but I have not been able to get that out of mine. I regulary shoot tighter groups at 50y with my Mossberg 1944 trainer and target sights than I do with my 2008 Mark II with 6-24x scope. The Savage even has a better trigger. This might be a break in issue, but groups have not tightened up yet at 1000 rounds. Pulling a patch through the bore, it feels very rough, even when clean. There are also visible concentric maching marks that can be seen inside the muzzle that cut through the lands and grooves less than 1mm from the crown.
If you are the type to appreciate a rifle for what it is, not only what it can do, and money is not tight, by all means get the CZ. I have seen some gentlelmen at the range getting phenomenal results out of 452s and Brooks triggers at the range.
According the discussion at RimfireCentral, the CZ 452s also tend to be slightly more accurate, on average.
