Unfortunately, Chilli57x hasn't returned after his first post to clear this up. I also have a rifle like the one Calhoun pictured (in 30-06) and it is indeed a
straight pull bolt in the style of a Blaser.
It was made by Oberndorf Mauser during the time period Calhoun mentioned and to add to the confusion between this modern rifle and the old Swede M96 of over a century ago, it's designated the Mauser M96 (1996).
These photos are NOT of my rifle, otherwise it's identical:
