I have, or have had CZ527's in .22 Hornet, .222, .223 and 7.62x39.
The hornet has always single loaded a loose round without issue, as did the .222.
The .223 and 7.62x39 did not, the .223 was fine if using a single shot loading tray, not so the 7.62.
The .223 needed no more than a light polish on the front edge of the extractor to work perfectly, loose round or from the tray.
The 7.62 I was surprised to find had no lead angle on the front of the extractor, and was actually very sharp inside and out.
It also badly marked the brass, leaving a sharp 'spike' of brass sticking out from the rim.
I removed the extractor and gave a simple deburr with a fine diamond hone, followed with a polish using a small fine scotch-brite wheel on the dremel.
Rifle now feeds perfectly no matter how you do it, magazine, loose or loading tray, and no more brass damage.

Neil.
