I just boughtmy rifle back from the gentleman that I sold it to a year ago. When I purchased it back he added a Bushnell Banner 6-18-50 scope to it which is a good scope but I would like to upgrade come spring time to a higher end scope. The three that I am debating in my price range are Nikon Buckmaster 6-18-40 with the BDC reticle, Burris Fullfield II 6.5-20-50 with Ballistic Mil-Dot reticle, and the Bushnell Elite 4200 6-24-40 Mil-Dot with a free 5" Sun shade. Just so you all know I have a Browning A-Bolt 7 WSM. Can someone please help me with my future purchase?
