it seems the cz did more than just a bit better.... the norc had overal decent hits, but no holes overlapping.. where the cz, except a few shots pulled, they were all ontop or next to each other... that actually pretty good...
I would have been concerned about overal realibility over the accuracy.. but with your above report...and I understand this is your test and not an official test comparison, but going with yours for a moment...,
I can see where shooting for fun would be great gun, but if for any type of competition, I'd go with the better brand...accuracy or lack there of, will cost you big time if shooting smaller targets, steel plates, etc..
