Dose anyone have a Nightforce NSX 5.5x22x50mm zerostop? I about to make the plunge on one of these scopes. I have a co worker that dose long range tactical shoots and he swears by this scope. Just wondering on the redicale choice, which would be best for long range hunting? He tells me the BDC would be a waste and I should go with a mil dot type. He says I can then use it on multiple guns. Any suggestions would be great. Also I was wondering what scopes would compare to the performance of the NSX?
