I never even got that far with IOR scopes. Have tested them twice in the past 6-7 years and have not been that impressed with the optics. This of course may differ from other's opinions but my tests were with optics charts and not just general impressions. I pretty much concluded that for a practical hunting 6x there were other options, considering optics, weight, etc.
