The 163 in 1.5 gr I would run as a lot. That's only .1gr of equivalent powder difference, and even if you weigh each powder charge, say on a balance scale, that's about the best resolution you could hope for in powder anyway. (+- .05 gr)I've actually got 200 cases. I set 37 aside to end up with 163 cases with a variance of 1.6 grains. I usually weight sort within one grain but I've never dealt with a case that weighs 320 grains.
Nightforce has great tracking capabilities, they are rugged, a bunch of elevation, holds zero forever, and reticles are designed for long range shooting. So if you are looking to shoot long distances constantly, then you need a scope that can take the abuse. -- gilmillan1
Nightforce is such a solid combo of reticle, available elevation, glass that is good enough to shoot at the longest range you can dial. Nightforce has bullet proof construction that can handle the incidental horse rolling or some other rodeo action. -- bigngreen
The total package. Nightforce is the best I have used as far as turret feel and solid detents. I have never had one that didn't track right on and always return to zero. Nightforce NXS is the best value for everything I need. -- Broz
