I think you will find this new scope "very" interesting. It was also ranked #1 by ShotgunWorld.

I already bought one for my Muzzleloader and its brighter and clearer than my Nikon and can take a pounding with 150gr of powder without loosing zero. I will be buying a second one this week for my Shotgun.
