I've got a 6.5 x 284 I've had for a while ,never shot and never mounted a scope. I have a new Nightforce BR 12 X 42 that I'm not going to use . I will be shooting to 1000 yards and sometimes more. I was thinking a .1 Mrad Vortex PST 6 X 24. I have a 20 MOA base on the rifle. I only want to make the right choice once.
