@PetahW: You're absolutely right about the length of the shortage. If I recall correctly, it started here in arizona sometime in 2012. That's 2 years. Even if manufacturing production increases, I still think there will be shortages, because people will continue to hoard in case there is another future shortage. This may have created a market mindset. As you calculated in another thread, it doesn't take too many people to eat up excess production. Maybe things are starting to ease, though. .223 and 9mm seem to be getting plentiful and I can now find 12 gauge buckshot on the shelf.
@yotesmoker: As for selling the CZ, another forum member, "cheapshooter" has the tag line "Never sell or trade anything". Good advice. In my fifty years of buying and collecting guns, I've probably sold about 15. Without exception, I pretty much wish I had everyone of them back. The CZ is a quality rifle and who knows about its availability in the future. So, unless you need the money or absolutely hate the CZ, I would keep it.
