I'm running a 20 MOA base right now, and 2600 FPS is very doable with my set up...starting to think the 65 MOA of elevation isn't the problem I first thoughtAt 2,600 fps muzzle velocity (just a guess, seems reasonable for a 308, I've never loaded the 185's)...you'll only need appx. 33 MOA of adjustment...you said you had a 15 MOA rail...the Viper will do the job.
I pretty much decided on getting the Viper, but in SFP instead of FFP....don't feel like paying an extra $100 for it when I can use the subtends they give and do the math pretty easily for different power settingsI'm not even looking for a new scope and this thread has me confused which way i should go......... lolgun)
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
