I am a new member, and a passionate hunter as all of you. I live in Quito, Ecuador, South America. I hunt whitetail deer in the Andes Mountains, and I frequently have deer that I could shoot out from 500 yards or more. I own a Winchester Model 70, 270 winchester, Pre 64, 22 inch barrel, worked on beddings, full floating, and trigger. I reload my shots which I learned by myself reading books and articles. Not a lot of people is interested here in hunting, and presicion shooting and reloading. My longest shoot has been to a 8 point whitetail buck and 325 yards, ranged with my Leupold rangefinder. I know my limits, and I am very interested in learning about long range shooting. Need advice on what scope would you guys recommend between the nightforce 3.5x15x50 or nightforce 5.5x20x50 or a Leupold Mark IV 6.5x20x50. Need also a spotting scope, what would you recommend. Thanks for the advice. If interested in hunting in Ecuador just let me know.
