Just bought a Savage 10fcp HS precision. I'm very new to long range shooting and know nothing about scopes or how to set them up. Im looking to shoot 100-600 yards and I have a budget of $600-$800. Any recommendations on scope brands and models I should be looking at?? And I also want to educate myself on scopes, long range shooting and technique. Any good forums or article I could read up on??
