Along similar lines, there are still plenty of people complaining about short targets being pot luck because they can't see them properly. Usually you'll find those complaining are using a relatively high magnification setting and/or a relatively long PX setting. No one is forced to use any particular scope, mag setting or PX setting so the argument is spurious. This doesn't mean that they have to go to the expense of a Leupold MK4 though. A common or garden 3-9x40 with an appropriate mag/PX setting will have you seeing every target clearly.
