There has been a great number of posts regarding which rings to buy for Brand "X" scope. While every single scope on the market has a different sized objective bell, it is seems to be massively confusing which rings to purchase. Not every manufacture uses the same measurement values for low, medium, high, and extra high classifications. This post is to help alleviate some of the major confusion.
Here are a set of pictures to denote two different medium ring sets. They are the Warne Permanant attach and the Burris Zee.

It is not very difficult to figure out the height for the set of rings you wish to purchase, in combination with the bases you are using once you do two crucial measurements. The Savage 93 and Mark II have the same diameter receiver and base height from the factory. The height of the stock bases are 0.141". It is measured at the thinnest portion between the receiver radius and the top of the base. For a Ruger 10/22 using the factory rail, it is 0.310" from the top of the base to the top of the bull barrel.
If you do not have a good digital caliper, may I suggest this one for a modest investment. Please choose whichever one you feel like purchase, just get one. You can usually find the dimensions of the objective from the manufacturer or from sites like MidwayUSA. You want to measure the largest part and most rearward part of the bell. It is the piece you are trying to have enough clearance to operate.

Setting a goal of .125" separation between the lowest point on the scope and the top of the receiver/barrel is preferred. You want the scope to be as close as possible without touching while allowing the adjustable objective (if your model has one) and lens covers to function properly.
Here is the formula: (Base height + ring height) - (Objective bell diameter/2 - Tube diameter/2) = Scope clearance.
The goal is to solve for the ring height. I will use the Bushell Elite 3200 4-16x40AO as an example. The specifications are:
To work out the bare mininum ring height you have run (Objective bell diameter/2 - Tube diameter/2)- Base height. It looks like this
To help you make a very quick decision as to which height to look for, I have included the following values: stock bases, 1.000" scope tube and 0.125 clearance"
If you are working with a 30mm tube, you have to factor in a tube diameter of 1.181" diameter. Here are the suggested heights:
I hope this allows you to make a more informed ring purchase for your Savage. Sticky this.

The goal is to solve for the ring height. I will use the Bushell Elite 3200 4-16x40AO as an example. The specifications are:
Objective bell diameter: 53mm (2.087")
Tube Diameter: 1.000"
Stock base height: 0.141"
Tube Diameter: 1.000"
Stock base height: 0.141"
To work out the bare mininum ring height you have run (Objective bell diameter/2 - Tube diameter/2)- Base height. It looks like this
(2.087/2 - 1.000/2) - 0.141 = 0.403"
Add 0.125" to give the proper clearance and you need a ring height of 0.528". To get the correct measurement, the height is taken from the smallest distance between the scope tube and the base of the ring (where the ring sits on top of the bases). You could vary this figure plus or minus .050" depending on preference. Using my favorite brand of rings, the high Warne Maxima Permanent-Attachable rings are 0.525" high, giving me an affective scope clearance of 0.122" I am partial to this ring set since there are no exposed bolts to snag, use two bolts to put tension on the base, and they have a very clean appearance.To help you make a very quick decision as to which height to look for, I have included the following values: stock bases, 1.000" scope tube and 0.125 clearance"
