Hello Gunclub,
The more I shoot, the more I believe each gun is an individual with its own tastes and preferences. I do not own a CZ 452, but another manufacturer's 22 LR rifle. A friend of mine has a rifle exactly like mine, same make, model, caliber, everything. We never compared dates of manufacture but I believe they should be close as we both got our rifles from the same store on the same date. My rifle likes Federal 40gr solids and doesn't like Federal 36gr hollow points. My friend's rifle is exactly the opposite.
The good thing about 22s is that ammo is very affordable. I'd suggest getting a box each of several different types of ammo and trying them out to find out what your rifle likes.
Best,
Marc
