A hunting partner got his ass kicked by a bull moose a couple years ago in large part due to a Kimber in 338WM failure to fire. Wounded bull came at him from real close and he stumbled backward and attempted to shoot while lying on his back. Factory load, just a click...
Extreme excess "headspace" at the shoulder (+.125") and enough excess at the belt that a no go closes with slight stiffness.
Kimber CS yawned...
