I am shopping for a scope for my new Varmint rifle(ground hog's). 500-600 yards will be my longest shots. My budget is $500-$1,000. My number 1 priority is tracking. Number 2 priority would be clarity. Light gathering is not a real issue. I have been looking at the 16X IOR, and the 6.5X20 Zeiss conquest. I am looking for suggestions. Who makes the best scope for tracking?? In my price range?? Tom.
