I assume those scratches could only be caused by the barrel? CZ wants me to send the gun in for 4 to 6 weeks but I can't bear to part with it for that long! I just got it! If I request a replacement barrel might that fix the issue?

In the photos you posted of the scratched round... how was it chambered?
From a magazine?
A round dropped into the chamber & the slide dropped?
Have you pulled the barrel from the slide & dropped a round directly in the chamber? Does it hang up or drop in freely?This could help tell you if it is the barrel or some other part of the pistol.

It was chambered from the mag. The mag is not scratching.  It looks like the chamber mouth or internals.  I tried polishing the mouth with 600 and 1200 grit sandpaper, but it had no effect.  I'm too afraid to try polishing the chamber itself.

Have you tried the plunk test as Cntrydwwwg suggested? With the barrel removed from the slide? Until you've done that you haven't isolated the problem to the barrel/chamber. Blacken a round w/ machinist's blue or black marker & let a round drop into the chamber until it is either fully chambered or you feel it hang up on an obstruction. Remove the round noting the orientation & look for any scratches. If it's scratched at 3:30 look in the chamber at the same point for a burr.

Update: sent the gun to CZ and after 4 to 5 long painful weeks it came back with a reworked barrel!  Took it out and put 100 rounds through it and it functioned correctly!  I shot the best group (various timed drills with buddies, all but one of 50 shots were in the center mass and head of IPDA target) Ive ever done.

The funny recoil issue was fixed as well.  The fresh round was dragging and causing a two-stage "kerchunk" as the slide slammed home, which made recoil impossible to compensate for.

Since going to the factory it all seems fixed!
