I do not have any information on your BDC Banner, but it would my suggestion to set the BDC @ 0 and sight the scope in normal if that can be done.

Start at 25 yards and get it on paper then 1" high on the dead center. Move to 50 yards and shoot a group hopefully it will be around 2.5" high. Then finally to 100 yards, you will have decide your heigth there or maybe with the BDC you shoot dead on and use BDC from there. I have not personally looked at BDC because of the different weights of projectiles I shoot or even the differences in powder.

If you can not get it on paper@ 25 or hold a group @ 25 you are into a different set of problems...

Hope it works for you...
