I'm picking up a new Win Model 70 in 300 WSM for hunting everything from Sheep to Elk. I'm new to long range hunting as I haven't taken a game animal past 300 yards and haven't used a scope with a top magnification higher than 9 power. What optics would you recommend for big game hunting out to say, 600-700 yards? Assuming I'm able to get the accuracy and confidence needed to make good hits at those ranges. Im hoping to keep the price of the scope under $1200? What are your thoughts on this setup and recommendations?
