I am looking to purchase a scope for a deer rifle and have settled on a Nightforce. I am looking at either the SHV 3-10 or the NXS 2.5-10. Aside from the obvious differences (adj. parallax, capped vs uncapped turrets), they seem to both fill a very similar role. I really don't have much experience with rifle scopes and I'm looking for some input on whether the NXS is worth the fairly significant jump in price.
