Has anyone had anything to do with this scope? I know there new but looking at getting one. How does this sytem work and is it reliable? Most likely will be going a a 300 win mag. I currently have a burris with a mil dot in it. I love it, but it confuses the hell out of my dad when he hunts with it. The kahles, from the looks of it, is just turn the knob to what distance you want and aim spank on.
