1 scope/1 Rifle - multiple ammo types at the range

What are the ways you can use your scoped rifle if you went to a range with 4 or 5 types of ammo that have different velocities such as subsonic and supersonic, and varying ballistic coefficients? Can you zero the scope at a bench rest on a paper target with one type of ammo, and then just leave it zeroed for that ammo and see where the other types of ammo group on the same target and record the MOA differences to know how much to adjust windage/elevation to zero your scope for each type of ammo? So if you tested 4 different types of ammo you would have 4 different zero settings, and you can switch to them when switching between ammo types? Or do scopes tend to be inaccurate when doing this because of changes in windage/elevation turret clicks, and switching between them? I realize that windage and elevation adjustment is used to initially establish zero, and windage/elevation is also used with a ballistics calculator after your rifle is zeroed to make changes to distance to target and/or environmental changes using the same ammo it was zeroed with, but can windage and elevation adjustments be used in the way I described, to establish zero settings for different types of ammo starting from a baseline zero from one type of ammo, so you can switch between ammo?

I suppose another way to go about it if the goal is to still hit bullseyes after each ammo's point of impact group is recorded from a previously set zero is to have a reticle with detailed hashmarks for windage/elevation such as a "tactical" scope with good turrets and magnification and adjust the point of aim on the bullseye to the differences in MOA for each ammo type. This would avoid turning turrets for each ammo type. Does that make sense? Not as fun as lining up the crosshairs with the bullseye everytime after clicking turrets, and more like practice in a shooting situation where you're using holdovers to compensate for distance changes closer and further than zero like you might for hunting.

Yes, it is possible, if you have a quality scope with very good repeatable turrets. I am talking NF, Leupold, and Sightron kind of quality here. Good luck and keep us updated.

Sometimes I put one target up and leave it up while putting my other targets individually over (lined up as precisely as I can). The one that stays will give you a group of all your loads while your individual targets will show individual groups.
 
Digital day/night scopes often have a "file" for each rifle(moving scope between firearms). You could create a file for each load and run the scope by load. Scope would "automatically" adjust the zero for you.
 
You know it is so why do you need it explained?
I know it's important but I may not know all the reasons. The reason that comes to mind for me is, when choosing a scope for this application, a BDC scope with MOA or Mil hashmarks in small increments will come in handy, especially when switching between ammo that has similar POI. Hashmarks for windage are important if different ammo shoots left or right. Distance is important because scopes vary for their utility...some are for longer distances than others and will offer higher magnification and greater measures of MOA/MIL for targets at further distance in the reticle. Rifle and cartridge is important for instance a straight wall cartridge will lose velocity quickly and have greater bullet drop sooner therefore a scope designed for 500-1000 yards is not necessary for a straight wall rifle unless you like adjusting for 25 MOA and losing 50% of velocity at 500 yards.
