There is a difference at the high end of the scale, but for what you discussed initially, you would never notice the difference.


You're talking a 3x9x40 for 100-300 yard shots in your post, 1" should be fine. It will also be less weight than a 30mm and you can get it lower on your gun, also a plus, yeah it's only a .15 or so of an inch but ...
If you were wanting 30mm, I would go on and step up to 50 or 56 to let the larger tube run.
