[QUOTE="bruce_ventura, post: 926073, member: 34084"] I would not recommend anything larger than about 70 mm for sighting targets at shooting ranges. Even without wind and any apparent mirage, shooting ranges have high turbulence in the air. Turbulence happens when the optical path is over flat terrain and the sun heats the ground, causing the ground to have a different temperature than the air. Hot air from the ground rises into the cooler air above it, causing turbulence. This turbulence causes the image to become blurred. A 60 mm objective is about optimum for most range shooting conditions. Increasing the objective size merely collects more blur. The Leupold SX-1 scopes are about the best I've seen in the $300-400 price range. The resolution is similar to ED scopes costing 2-3 times as much. Also the eye relief is long enough to wear glasses.
