I recently purchased a Nightforce NXS 12-42x56 for F/TR shooting. I was using a Hawke 6-24x56 ($450 scope) that worked very well. I was hoping to get better clarity and focus at longer ranges with the Nightforce. I see no difference in the two up to 22x power and neither focus well beyond 500 yards unless I turn the power down below 20. I was hoping to use the higher power of the NXS on cooler days to see better at longer distances. Is blur what I should expect with this scope over 22x and beyond 500 yards? Are there other high power scopes that are clear in these conditions?
