I have one also. A 5.5x-22x-56mm NXS, although I forget the reticle name (it's like an open mil-dot).
Very big and very heavy, but optics are great, tracking is excellent, and the illuminated reticle is arguably the best in the business.
I have it mounted on my Sendero SF in 300WM, which that gun itself is very heavy. Combine that gun with that big and heavy scope, and you have enough weight to hold down the space shuttle during take off.
That's really not of a big concern to me, though, because I do a lot of stand hunting from box blinds. But if I had to walk around with it, I would rather leave it behind and hunt with my bare hands.
