G'Day Gryphon,

I was looking up some things the other day when I came across www.thegunsmiths.com.au and they have a P/Hale ? in 7mm Rem Mag for sale. I don't know if this is a Magnum length magazine but at least the bolt face is correct for your needs.
Click on "Guns In Stock", look for Manufactures on the Left hand side of the page, then scroll down to P/H, click on that and up it should come.

Hope this helps.
