I don't know why folks are referring to their rig shooting 1200 when we're talking about twice that far which becomes an exponentially more difficult set of requisites. I'm not griping but it's meaningless in this conversation. Everything magnifies at those ranges and the overall optical performance required to resolve targets a mile and a half away is not what you need or can get by with at 1200. One should be optically comfortable when behind the glass and not straining with CA, (chromatic aberrations) casts, edge focus and resolution. A super crisp and clean reticle at high magnification is essential. To shoot well you have to be able to relax everything. With that said, in your price range, the Vortex Golden Eagle, Razor GenII, used Nightforce, Kahles or S&B. (Tangent Theta is my first choice but twice your budget) You may consider a Sphur mount as well, they are expensive but with as much recoil as is in the Cheytac I would not settle or compromise anything.
