*Beware of using Winchester ammo or Winchester primers in the CZ 527 - the CZ firing pin spring lacks the oomph to reliably ignite the Winchester primers.
I contacted CZ USA about this and they sent me a stronger firing pin spring so the problem went away. [/quote]
I called them about the problem, too and they told me to either send in the bolt and they'd upgrade the spring under warranty, or pay for new spring and they'd send one out to me to install. I haven't gotten around to either yet.
