Here is a pic of my 500 yard hunting rifle that doubles as a defence rifle it is a shortened to 21" barreled Rem 700 LSS in 375RUM.
With the Leupold VX3 4.5-14X40mm B&C reticle scope mounted I consistently group 3 260gr Accubods @ 3020fps into 6" @ 500 yards.
With a 200 yard zero the second B&C reticle line down is dead on @ 460 yards.
Reason it is not my 600 yard rifle is I just haven't had the time to figure out the trajectories yet and actually do not care to.
With the scope removed I install an XS Sights tall Weaver ghost ring backup sight gives me cloverleaf 50 yard groups with 350gr TTSX @ 2440fps and 6" 6 shot 200 yard groups.
