Taking my 7mag, 3021 fps, 200 yd zero, 168gr VLD Hunting, 1000 ft elevation I show a drop @ 500 yds of 34.1", at 7000 ft elevation @ 500 yds jbm shows a drop of 32.5". It appears almost irrelevant me, but I may be missing something.
You're not. There are several reasons that BDC turrets might not be the best choice for true LR work but sub 600 and one load/one rifle isn't it.
The biggest problem with the popularity of BDC turrets/reticles is that a great many believe they are all they need to kill reliably out to whatever marked range without actually learning to use them correctly or even learning how to shoot correctly.
