My brother and I just bought Kimber Montanas in 300WSM. We hunt deer, antelope, black bear, and elk everywhere from the black timber of Washington to the desert of Nevada. We are stepping up from our usual 3.5-10's to the VariXIII 4.5-14. My question is 40mm or 50mm and which reticle - Duplex, Heavy Duplex, or Boone and Crockett? Any advice on elevation turrets for these scopes? Thanks in advance for the help! I have learned a great deal from the people on this site.
