I have decided it's time to upgrade my scope on my 300 Win mag. I currently have a vortex viper PST 4-16x50 mounted on top. I am looking for something with repeatable turrets, quality glass, FFP if it has to be a mil / moa system. I'm not sure about mil or MOA reticles. I'm considering just a plane crosshair or plex as I like to dial my scopes. My ranges currently are 100-500 yards and hoping to reach 1000+ next summer (which will then allow me to upgrade rifles) Give me some of your thoughts. My budget will be $2K.
