Should re-center my scope when changing rings?

I'm taking a scope off a rifle and remounting it.

Should I re-zero the scope to make sure I have maximum control on elevation and windage in the new rings?
 
Zero should be rechecked. Variance depends on type of mounting system as well. Some are designed to return to original zero. Should always be verified though.

Maybe I used the wrong word.

I certainly do not expect it to remain zeroed. What I meant was adjusting the dial controls to centre before mounting the scope.
 
I don't know what resetting the adjustments to the mid-points of their adjustment ranges would accomplish.
Mount the scope, zero it, see if you have lots of left and right available, and how much elevation is to be had.
If there is an issue, you will have to look at shims, adjustable mounts, ring inserts, etc.

Unless OP is using adjustable rings, either Burris or Leupold etc. If you're using fixed rings, then resetting the scope achieves nothing at all.
 
Stick it on the rifle and check it with your bore sight.
Decide from there whether you're going to do the twist dial dance.

As mentioned, sometimes you git yer arse lucky.
 
Resetting the reticle to centre is only worthwhile if you are going to need that much adjustment. I would mount it as is and bore-sight to see if that is likely.
 
If you want to recenter before you remount in new rings it can be done by holding the scope to a mirror. Hold it flat to the glass and you will see 2 sets of lines. adjust till they show one set. Takes no time at all. Its not necessary though if you are going to boresight after install.
 
If set-up has windage adjustable bases, then centre the adjustments and do the rough sighting with the base screws. No need to be super precise about it, count the turns from side to side and go back half. So, if there's 6 turns go back 3. F you don't have adjustable bases, or the rarer adjustable rings centering the scope first accomplishes nothing. It will end up in the same place regardless.
