I knew I couldn't afford a brand new precision long range rifle scope, so I went shopping for used. There were two scopes that interested me at Wolverine, a Nightforce and a S&B PMII. After looking through both scopes the S&B went home with me. I don't recall what the magnification of the Nightforce was, but the S&B is a 4-16X40. I prefer mils or cm@100, which amounts to the same thing, over MOA since the numbers you have to work with are smaller, and I appreciate the full range of elevation adjustment in a single revolution of the turret. Consider the choice of a reticle with multiple hold-offs, like those designed by Horus. My mil-dot reticle works well, but doesn't provide a windage hold-off opposite the elevation point, except at center. The hold-offs are particularly useful when you're shooting in rapidly changing conditions.
You probably have to use a sloped base mount, and although I already had a 20 mm Badger on my target rifle, I've bought nothing other than Near for the last few years. Near can provide tapers of 10, 25, 45, and 75 minutes, and mounting hardware of 6-48 or 8-40 as you prefer.
Oh, by the way, my rifle is a 1:8 twist .308 ( fast spinning bullets tend not to destabilize as they pass through transonic to subsonic velocities) with the lead cut long, so VLDs and Hybrids don't extend below the shoulder of the case. I've used this rig out to 1300, under ideal sea level conditions (overcast, warm, humid, zero wind) and intend to push it out to a mile.
