This other Bushnell scope is a pretty good buy (price $200-$250) http://bushnell.com/tactical/rifle-scopes/ar-optics/1-4x-24mm-throw-down-pcl BTR reticle, FFP, illuminated. It works really well on my 300 AAC, and when zooming in/out, it becomes almost like a red dot sight at 1x, so it's handy for quick target acquisition with both eyes open, and the BDC works well at 4x if you know what the drops are (I too, use Strelok Pro to determine the ranges). Since it's FFP, the drop markings are consistent throughout the zoom range. I don't think so. I've used it all over the place with or without data service and it has worked. I actually keep the data in several saved presets so it pulls up quickly.
