I am going to purchase a Sightron 2 Big Sky . The question is which will be better for long range hunting; the 4.5-14x44 or the 6.5-20x50. The 14x has 80 MOA, the 20X has 60 MOA. I need apprx. 20 moa @ 800yds and 28 moa @ 1000 yds so I should be ok with adjustment range in either scope right? If I had to I could use Burris *** align inserts with the 20X scope to center my optics better. Do I really need 20X on deer sized game at longer ranges? Thanks again for your inputs. Brian
