Ok i know this is prob. the 1,000,000,000 time this has come up but i cant find the info i am looking for. I am shooting out to 600 yrds. at our local range what power spotting scope is needed to see the holes in paper. the only thing i have found is that you cant see the holes from that far with any power. If this is the case would a 20 to 60 by 80 work for long range shng as a norm for say out to 400 to 500 yrds?
