The answer to the OP's question in my experience is 'yes'. I am always discussing this with new club members along the lines of 'why on earth are you fitting a 6~24x50 crappy scope with side parallax adjustment wheels when all you are doing is shooting on 12x on a range that is 55 yards long at maximum. It just isn't necessary. I suggest to them that they would be better off buying a really nice-or at least 'better' scope with a maximum of 12x magnification. Also although a 30mm tube lets more light through than the humble 25mm this is more than enough for shooting at any air rifle range. Sadly few listen but that is up to them. The 'arms race' in gun and glass continues and will continue for as long as we shoot. Pride of ownership of high end (that is high price) kit will be with us for ever.
