OP here, thanks for the many replies. all my current scopes are 1" tubes. most high end scope i have is a 3-9x40 Conquest. on my last several hunts the deer have only appeared at dusk in the treeline... the last time i was hunting with a Leupold Vari-X II where i lost the thin crosshair. I am going to need the illumination. 30mm because those are the rings i bought for the new 300 H&H Browning X-Bolt (I know, tail wagging the dog). I want to step into 30mm tubes and this will be the first one. Will take a look at those recommendations. I really want to stay under $500, but would stretch it to $600 if need be.
