What happens to zero when.....

[Sebrock]

if I switch to from a 0 to 20MOA scope ring set up (base is already 20), will my elevation drop by 20 MOA exactly that before I try to re-zero, I can just make the adjustment on the scope first and pretty much be almost there?

It will shoot 20 moa lower from the current zero.

That’s what I figured - TY.

Well, you’ll find out just how close to 20moa was built into the scope mounts. You'll get the difference between the old and the new, what ever that is, and it may not be exactly on the same wind zero either.

Thank you. Yes I figure I will have to re-zero but hoping it’s as easy as winding down 20 MOA and then make some minor adjustments after that. I’m going from spuhr mount to spuhr mount so it will be very interesting on both elevation and windage. I will be disappointed if it’s more than .1 or .2 mils. We shall see.

Spuhr makes some quality mounts. But don't be too disappointed if you have to move it more than .2 mils. At the length of that mount, 4.76 inches, .1 mil means a tilt of about .00025 inches.

Sorry should have been more clear - was talking about windage. Given their whole bolting system and repeatability from taking on and off. For the elevation, Im just going to dial down 5.8 mils and should be close on paper but Im sure I will have to adjust some more - Im just thinking that the windage shouldnt change so much if both mounts are equally true. No?

Maybe so. Let us know how it works.
