need help on mark IV scope
I have a remington sendero .338RUM. I bought a mark IV 6.5 x 20 leupold scope. I just need help using the target turets. How do I get my scope to where all i have to do is dial the scope or click the turets up to 5 and hit at 500 yards, or click on 6.5 to hit at 650 yards?
