I don’t know if the OP knows the difference between first and second focal plane and how it affects BDC.
I sure do. That’s why I asked above if anyone has experience with the Burris Veracity scope with bdc in ffp vs the 2nd ffp that most hunters are using. I don’t particularly care for having to know the bdc yardages at every power magnification. Seems it would be easier if bdc yardages remained the same at all power settings.
