What is the objective diameter? That may dictate what height rings you need.
Edit: never mind, I should have read 2 posts further... 44mm.

Step 1 - Go to the store and buy a simple ruler,
Step 2 - Mount your rings and scope on your rifle - make sure the bell of the scope doesn't touch the rifle or the Pic rail & use the lowest rings possible,
Step 3 - Forget abut the height of your rings. Measure from the center of your rifle bore to the center of your mounted scope. That's it. That number is what the scope guys need to get you a custom dial. I have done this process countless times very successfully

Nah, I have a bunch of 30mm tubes and they sit with Warne Mountain Tech rings on a 20 MOA tail and they're all in the 1.9 range.
A little context for the OP. In the scheme of ballistic calculations, of all of the inputs, the exact/precise scope height calculation is one that has the least impact. If you are within .125 - .25, you should be OK for short range. Just follow the mid bolt to mid scope measurement method.
Understand, CDC's are neat and convenient on a standard hunting rifle. Know the distance and dial the scope. you'll be close.
However, they are only as good as the ballistic and environmental information used to create them.
Assuming you are not reloading, if you change ammo, the CDC is changes. Heck even if you buy the same ammo, the velocity may be different from box to box, so the CDV changes. The zero at 100 must be right. Also, if the environmentals change, change in altitude, temperature, etc. , the CDC changes.
Not trying to beat up CDC's. Just trying to point out how an exact scope height has little to no impact compared to other inputs.

Mark 0 to 5 inches on waal Put your barrel against a wall at 0 look thru scope mark where cross hairs on measurements

I have just gone through the same process myself. I have an X-bolt 300 WSM left hand. I measured the diameter of the action at the front mount and divided by 2. I measured the diameter of my vx5 scope and divided by two. Then I added the height of the Talley low front lightweight ring which is 0.440". This all comes up to 1.635".

What would be the model of the Leopold scope?
OMFG how is this thread still going and how is there so much bad advise. Get a tape measure and measuer from center line of bolt to center line of scope.
FFS guess if you want, I'd call it 1.75" with out even looking it's going to matter less than the atmospherics and probably lot to lot variation of your ammo because if you don't have calipers I hope you aren't reloading.

44 mm is 1.72 inches decide by 2 = .865.
So 0.90 rings would clear the action. And give room for the scope bell should the barrel be tapered from the action..
Simple math....

Exactly they've been very helpful to me in the past.

??? This is an easy measurement. I don't understand your problem.
My Bushnell Elite 4.5 - 18 x 44 scope in Talley rings, (which I assume you have for the unique Browning 4 bolt mounts) brings that scope center to the barrel center of my 6.5 PRC Browning X-Bolt Pro to 1.5" exactly. I used a simple ruler and straight edge to get this measurement.
1.) lay straight edge top edge on centerline of the barrel back to the scope rings (tape it on if necessary)
2.) measure from the gap in the scope rings to the top of the straight edge. VOILE'! You now have that distance measured.
