Hello

I have a Savage 10 Predator Hunter in a .243 Win. I bought a Sightron SII 6-24x50 for it. Sightron has all the specs for their scope so I know the outer diameter is 2.28". However I'm trying to figure out what the scope mount to barrel taper height might be. I'm trying to get a DNZ GameReaper on it. The optics place told me to get a high mount but I feel like a medium mount would have done the trick.

I have been trying to use this site: http://www.mil-rad.com/scope_ring_calculator with:
Objective Bell Diameter: 58mm (approximately 2.28")
Butler Creek Cap: 2mm
Scope Ring Height: Height of mounts from top of receiver to centerline of scope tube for DNZ mounts are - low .92″, medium 1.05″, and high 1.17″
Scope Mount: There is no rail needed for DNZ mounts so I think this is zero for the scope mount.
Barrel Taper Height: I have no idea what it is for the Barrel Taper. This is why I'm here :).

Any insight on how I can perform this calculation?

Thanks
Sam
