As stated in my previous response, I have used numerous chamberings and numerous loads from high velocity and high BC flat shooting rounds to much slower rounds and I am always +/- 2" from where I am aiming. So, what you should take from this is even you should be able to utilize this system without having to mess with your magnification. You will need to keep it on the same magnification to keep it consistent over 200 yds.
So, if you want to shoot quicker and without relying on a chart, then get the any ballistic reticle you want and use it. FYI, I have looked at most of these Zeiss, Nikon, Leupold, Burris... and most are set for a typical 400 bc bullet going around 2800 fps = or about your typical 165 grain 30-06 or 130 gr 270, basically your most popular big game rounds. Again, I have used 600 bc bullets at 3050 fps and it works all the way to 600 yards. I don't change the power setting, I simply look at my drop data and match it, or what I would recommend is basically getting as close as you can on your 2 fartherst aim points(400,500 yds) and you will not be more than 2" off at 200 and 300 yards. The margin of error works better than estimating off one fixed reticle aim point like on a duplex reticle
