9Three,
Yeah, I'm certain that it was definately controlled feed.
I'd handled quite a few of the original push feed Mk11's which clients were using.
At that time, there were rumours that the Mk11 was coming soon with CRF, and I had also been told this by the gunsmith doing warranty repairs for Ruger here in Oz, but it wasn't supposed to happen for a while.
One of my regular hunter clients came out with a brand spanking Mk11 stainless in .308 and I never paid any attention to it for the first couple of days.
For some reason I ended up having a close look at it and when I saw the bolt face I had to take a step backwards and have another look.
It was definately CRF, and I double checked by cycling all the rounds out of the mag by just working the bolt back and forth.
I'd been around '98 mausers, pre '64 Winchesters, Brno ZG's and 600's and other CRF actions for quite a while back then, and was fully aware of what CRF actually meant and how it operated.
I remember thinking that I should film or photograph the bolt face to verify that I had actually handled a Mk11 with CRF. I cannot remember whether I got around to it though.
If I get time I'll have a look on the camera tapes from that era.

I would still be interested to know when the first Mk11 stainless rifles appeared in Gun Digest.
