I having a .260 built. I want to get a scope that I can learn how to adjust windage and elevation in mils and do actual long range shooting. This will be my first scope better than a leupold mark 2 or meanace (both are moa's). What are some features that I should look for, I dont want the scope to be advanced for a beginner (I will upgrade in the future if needed). What power would be apporiate, I want bigger than 3x is 5x power overkill. I would like a USO, NF, or Preimer. Can you help me out with reticles and models I am afraid of making the plunge blind. Some things to lookout for would be very helpful.
