I am ordering an XLR chassis. Their suggested math for scope rings is as follows:

(actual objective diameter/2) + .9 - (action diameter/2) - base height = required ring height

Can someone who has an EGW 41002 20 MOA for a Savage Short Action (4.4) measure the base height for me?
Can someone who has a Savage Short Action 4.4 measure the diameter of the action?

Thanks!!
