I am looking to upgrade my current scope which is a Leupold vx-2 4-12×50. It will mostly be used shooting off a bench at paper from 100 to 600 yards. It will also be used for whitetail hunting occasionally. My max that I would like to spend is around $800. I have been looking at the Leupold vx-3 6.5-20x, Vortex HST, PST 6-24x, and Sightron SIII 6-24x. I prefer MOA over Mil. How do these three compare and what are the pros and cons of each one. I would really appreciate any advice. I'm also open to other options that fit that criteria also. Thank you!
