Guys
I spent 30 minutes with the head of the Cabelas "Gun Roon" in Sydney Nebraska and this is the scoop on the extrator as seen in the paper manual. Those depicted in the manual futhor up in this chain are the Baikals and not the Sabatti. The Sabatti has a convetional looking large extractor with machined half circles for under the cartridge rim just as you expect them to be.

So this eliminates some of the confusion and surely my concern about that subjset.

With regard to regulating rounds, they are regulated using Winchester "Silver box" 45-70 300 grainers which of course means I will definately have to work up some loads as I do not feel 300s are accurate nor have enough stopping power for what I want to shoot.

Thanks All
TC
