Target acquisition is faster-with 40% bigger viewing area through the tube.
that is funny. 30mm allows for a more robust erector that has more travel. I personally think 30mm should just be standardized it doesn't really add any weight. for your average run of the mill hunting scope 30mm offers no advantage.
the big joke is the 34mm tube scopes. in many cases they have no extra travel than a 30mm scope and when we are talking needing to shoot that far. its likely to only take a rifle from say 1700 yards to 1900 yards.
