How I figure it: Measure or check drawing for height of rail above action centerline. Calculate barrel diameter at a point where the objective bell will be. Subtract half the barrel diameter from the action radius plus rail. That gives you the drop from the rail top to the barrel.

Take half the scope's objective diameter plus a few mm (for the housing and clearance) OR see if the manufacturer has an objective bell diameter listed; and subtract the measurement above from that. That gives you your minimum height to mount the scope without things hitting. You may want a step higher depending on your shooting comfort zone.

Basically, you're figuring diameters from centerlines of action, barrel, and scope, and getting a bit of extra space.
