I'm looking at buying a Nightforce 3.5-15x50 NXS F1 Scope but the choice in reticles is overwhelming. I realize the elevation and windage turrets are in MOA adjustments but not sure what would work best for a reticle. I want to go with something that will be easiest for unknown ranging of targets, hold overs, etc... Can somebody lend me some insight? I have no idea what I am doing when it comes to using a scope like these I'm used to Aimpoints and EoTechs for close range work!
