I have a Leupold vari-X III 2.5-8 mounted on my 458 win mag and when I crank the magnification to 8(clear picture) take a shot, look in the scope again and the picture is a little bit blurry, bring back to 2.5 and then back up to 8 and picture is sharp again….. any body had that happened on there Leupold and dealt with it? What was the issue?
