Molleman,
I keep an exploded shell from a Remington Plinkster that fired out of battery. That might be a lemon out of a batch of pure gold, but I will never fire that rifle again.
And I love my 452. Now that I am mostly recovered from a thoracic fusion, I plan on getting some trigger time on it. (By the time I got it, my back was so bad that I just couldn't bring myself to get out to the range much). Everyone has their own aesthetics and comparisons they look for in a gun. For what I paid for it, I am more than happy.
The only downside of the CZ is cleaning the bore when you first get it. That is the longest time I have spent, in my entire short life (32 years), cleaning a gun. It took forever, but that's probably because I didn't know what I was doing. There are plenty of threads on that very topic over on RFC (Rimfire Central), which is another great site to check out if you are still considering a .22.
