On the Sako they are driven onto tapered dovetails not mounted to a round action top.
Punching up from bottom will destroy the rail and possibly the action also!

Attach some beefy rings and scope... something sturdy like a nightforce and get an assistant to hold it muzzle up with the butt on the ground.
A couple of good swings of a bit of 4x2 about 1200 long...
