Re: Need advise on extreme range scope...
US Optics are the best thing going for true super-long range applications. I have two SN-9's - one for a .50BMG Windrunner, the other for a .408CT Windrunner and they cannot be beat - tons of elevation, finest optics of the market to my eyes, and built like a tank. They are far superior to NSX, but they are bigger, more expensive, and weigh more if thats your primary concern. If you want performance - go USO. I finally bit the bullet (pun intended) and checked out their products in side-by-side comparisons with Loopy, NSX, S&B, et al. I was so impressed I use USO exclusively on my rifles now.
