There have been several good suggestions so far. There is an easier remedy in light of the fact you have a BDC reticle. You often read people's assertion that a BDC reticle is only good for being set at one power. That is a misunderstood half-truth. The BDC reticle can be used at any power setting. It's just that the corresponding ranges of bullet impact are different at every power setting. Get the proper ballistic information for two different power settings and you've solved your problem. Run your information through a ballistic program which has your reticle and you will see the different yardages for points of impact at different power settings.
The major, and I mean major drawback of my above-mentioned solution is a precludes the need to purchase another rifle/scope setup. We don't always NEED an excuse to buy; but, it's nice to have one.
