I get why dialing a scope is beneficial, especially when your target is oblivious to anything around it. The scenario I am well acquainted with is you range the animal at 273 yds, then before you touch off he moves another 142 yds for some reason or another, maybe because he is running up a canyon or something. You can shoot, but only after you reset your crosshair.
Problem is, he's about to crest over a ridge now and stops just long enough for you to shoot, but can only do so after you range and rezero. With a BDC, you know all you have to do is put your 400 yd mark just below his back and let it fly. The additional 3 to 5 seconds to rezero may very well cost you that 195" muley.
Same principle as a slider sight in archery. It has cost me too many animals in the past...
It takes less then 3 seconds to spin a turret to 415 yards which is 2.4 mil on my 6.5 creedmoor. If your not ranging at those distances IMO you shouldn't be shooting either. It takes longer to figure out my bdc and holdover middlepoint at those yardages then it does to spin and squeeze.
I ran bdc for alot of year. Kentucky windage and holdovers worked ok. IMO past 300 yards its not the right way to do it though.
