Doctor Encore you have the right idea. I have a Luepold VX-III 3-9 with Long Range reticle. I sight in on 9X with 250 gr. Barnes EZ's At 150 yds. with main crosshair. the following indentions are at 200, 250 and 300 on top of post. It is almost right on at those distances. Shot an anetelope at 307 yds. and a deer at 295 yds. People don't believe it but it can be done with the right set-up.
Most of my shots are much less but I practice a lot with that rifle and load to be able to achieve that kind of distant. My TC pro Hunter has been accurized and trigger work has been performed by Mike Bellm. It really makes a difference. As always, field conditions determine if a long shot is possible.
