Hi everyone, I'm still learning about optics so I figured I'd post something here to try and learn more. I'm looking for a scope for Remington 700 7mm mag. Wanting to use it for some long range shooting (up to 1000 yards) and long range hunting if the situation presents itself. Any opinions on things like parallax adjustment knobs, first focal plane and second focal plane, how much elevation adjustment is needed, etc. The more info the better. I'm looking at $1000 as my max price. Thanks all.
