Good! Sounds like it’s a fun rifle to work with. As for the chamber, my understanding is that it’s to be expected thats it’s tight in a CZ. My 452 varmint certainly is. I’ve had no real problems with feeding into the chamber - except that I can feel how snug the fit is. And I’ve shot a lot of pretty crappy ammunition through it as well as better quality stuff. BTW my bore and chamber are tight enough that I bought a 17 cal cleaning rod for it. I won’t part with the rifle. Very accurate.
