Does anyone have any experience with these scopes? I've been looking at them and they impress me, a lot. I am thinking of putting one on a 7mm remington mag. But i was just wondering if anyone has ad any experience or knows anything about them. Here is a video of the scope [ame=http://www.youtube.com/watch?v=K8MEzra4B1g]YouTube - GreyBull Precision Long Range Hunting[/ame] . Please reply.
