The Millett scopes will be the first failure point. They aren't worthy of being placed on top of a high-power rifle in my opinion, as the gears, optical element retention methods, and other critical components are susceptible to damage just by opening the box, let along sustaining 50-80g's of recoiling force.
A lot of stock Remington 700's have accuracy and headspace issues off the shelf, which is why so many people send them off to be accurized-
* Action trued
* Barrel replaced with one that has more uniform bore dimensions, and is lapped well
* Trigger work
* Bottom metal work
* Action bedding (not an issue for you because you have the AICS chassis)
For your AR15, the op-rod system will likely be your accuracy headache point, since having additional mass attached to the barrel that reciprocates doesn't bode well for accuracy.
Wind will be the biggest determining factor with both cartridges as the distance increases. I've shot them both past 1000yds in no-wind conditions, where hitting is simply a matter of dialing elevation, but they are both significantly influenced by wind starting at the point where your wind-reading skills will become the limiting factor.
