If this is a hunting rifle I would go with a 3-18x Leupold. NF scopes are good if you're sitting at a bench dialing turrets all day long but they are heavy and the glass is surprisingly not that great. The Leupolds have better glass and weigh significantly less. The turrets are plenty repeatable. And for shooting inside 600 yards the CDS turret is the way to go. Just range, dial, and shoot.
10x is enough power to make 1000 yard shots on big game. 24x is handy when you're at the range and trying for groups on paper at 200 yards but it sucks in the field. I don't want any more than 16-18x for a hunting scope because its too hard to acquire and reacquire your target, which frequently is moving. For me its even harder to find a target when shooting prone.
I have used NF NXS, Vortex PST, Leupold VX-3 and VX-6. The VX-6 is without question my favorite hunting scope. The HD has some new features that make it even better such as the built-in level and illuminated reticle (TMOA is a great reticle). They say the glass is better too but the regular VX-6 has amazing glass already.
