CZ is notoriously tight, I was able to get these to run well. I prefer the flat point, a bit more accurate but finicky with brass. but the round nose
also worked well.
Something doesnt sound right ....... glocks tend to be very generous.....
did you smoke, or marker loaded cartridge to see where interference is?
i had issues with 147 flat points with certain head stamps, Having issues at the "hips"
