While I haven't done what your asking, in regards to 1 rifle and 2 scopes. I do use QD mounts on my ML's and typically myPOI is with in a 1" off where I left off prior to detach. Assuming you had 1 set of bases mounted on the rifle and a set of rings mounted on each scope I really can't see their being any difference then my experience. Certainly is Doable. However I personally would go hunting without testing after the detach or switch over.

BTW I use Warne Maxima's QD now. Have also used Leupold QR's. I have found the Warne's more consistent in terms of POI.

Good Luck
