Ok, I know this has been discussed before, but I'm really trying to hone in on buying the right scope. After much research I want to go with Nightforce NXS 5.5-22x50 but I'm still unsure of what reticle and whether to go with MOA or Mil. I've also looked at the Velocity 1000 reticle and don't really understand how they work when elevation and barometric pressure will constantly change. I'm new to the high end scope world as you can tell with these simplistic questions, so any advice would be appreciated. Might help if I tell you what I'm using and what I will be using it for. I'm shooting with a Weatherby 300 Wby mag. I'm going to be using this for about 90% hunting... elk, deer, antelope and whatever other tags I can get my hands on. Thanks in advance!
