  For one thing,the 30mm tube offers more elevation and windage adjustment.  Some say the 30mm tube is stronger also.

300 hit the nail on the head.  That's it.  more ups amd more beef.  No more light transmission, that is a function of Glass, Coatings, and Objective size and magnification.

There are several good threads under the F.A.Q. section of this forum on the 30mm vs. 1 inch issue.

The 30mm tube is stiffer than a 1" tube of the same wall thickness--but only if the length of the tube is the same length. Many 30mm scopes have longer tubes, where the stiffness advantage is lost.

How much of the tube extends beyond the rings also has an affect.

Well it does make enough W/E adjustment in my Black Diamond that I can get to 1000 yards without MOA bases.  But other than that, I agree with you.

I'm glad you agree. I was worried that I would have to ban you otherwise.
