I agree with most, not all, of the views expressed.

Assuming it has proper headspace (have a go-no go gauge?), try to identify why it is misfiring before applying any new solutions to a problem that may or may not exist. Light primer strikes could be either not enough firing pin protrusion or garbage built up inside the bolt. If the rifle has not been altered, this is a job for CZ to fix. If you have modified the firing pin, I would still sent it to CZ for repair.

If your rifle has excess headspace and you want to continue to use the iron sights, a gunsmith can set the barrel back a full turn (so that the sights are still in the correct place) and recut the chamber for the proper headspace.

I guess what I am getting around to here is to take the gun to a qualified gunsmith, explain the problem, and let him suggest the proper way to repair the problem.

If you do decide you want a new caliber, you will just be more confused if you ask others for the best caliber to change to because you will get other people's opinions. Get a copy of Cartridges Of The World, look through it, and decide what you think is the next cartridge. Or trade the gun in on another rifle.
