Hornady factory 300 Whisper brass issues

[Hoser]

Sounds to me like you might have a chamber that is cut a touch on the large side and the brass is a touch on the short side, headspace wise. Add the two together and your firing pin might not be long enough to light it off.

Glad to hear my brass is working though...

I would not use virgin brass in this bolt gun.

I have a friend who has 4-5 of his bolt action guns and he has the same issue. I loaded some 208's with federal match primers and lake city brass with NATO stamp and the problems went away. The Cz is a better platform than my remington 700 but I don't have to deal with the oal issue with the Cz mag and my gun is lighter. Cz is shorter with the reflex can.
