I don't know if I'd call it a "long range rig", its geared more as a "medium range" rifle. But my 280 Ack has a Leupold VX6 2x12 42mm With the bullets I'm using, I get to about 825 yards +/- with one revolution of the dial (20 MOA).
That's plenty far (for me) for targets, I'd probably limit myself to 600 yards for hunting.
