Schoolcraft,
Have your wife...
With both eyes open adjust the cross hairs to her (hopefully tight) group called "point of impact" (POI).
With both eyes open have her shoot another (tight) group and adjust the cross hairs to that group's POI.
Repeat until the POI and the bullseye is one and the same.
