Shell tool gives wrong dimensions?

I am trying to make a vacuum nozzle that goes from a ⌀1.2" to a ⌀0.5". I make two sketches, one of them offset above the first by 1 inch, and the bottom circle is ⌀1.2625" and the top circle is ⌀0.5625". I use the loft tool to make a cone-shaped transition between them, and then use the shell tool to make the solid shape a hollow cone with walls of 1/16" or 0.0625". I then measure the distance between the two circles, and I get 0.066218 in which is not 0.0625 in. How is this possible, and what do I do to fix this?
