I'm not sure what the folks at CZ have to say about this, but the one box of the stuff I ran through my CZ-527 didn't blow anything up, or even threaten to. However, it wasn't that great a deal, the accuracy was underwhelming, and reading miscellaneous stuff on the topic made me twitchy enough to decide it wasn't worth it.
(This same 527, somewhat perversely, seems to like the cheap S&B hardball. A lot. As in distinctly sub-MOA.)
