Re: 30mm vs 1" tube....what the deal?
The 30mm tube makes a big difference in field of view (low magnification doesn't hurt either).
This year I took a deer at 12 yards. I was using a Meopta 1.5-6x42 with a 30mm tube. Even at 12 yards, I could still see the entire deer right to the moment that I took the shot.
I am pretty sure that I would have had trouble making a shot that close with my usual 1" tube American spec scopes.
For Long Range Hunting, that may be a quality of limited usefulness, but it is something to consider.
