I'm wondering why there is such a huge difference in Field-of-View at 100yds from one manufacture to another.  I would think a 10x scope would have the same FOV at 100yds as the next.  I've seen anywhere from 9'-18' FOV at 100yds.  What am I missing?

This depends on a few parameters, objective size being one of them (scopes with larger objective lenses tend to have narrower fields of view).  The biggest effect is probably with the eye relief/FOV relationship.  Longer eye relief usually means narrower field of view and vice versa.
