I am still looking for a scope for my Savage in 6.5 Creedmoor. This will be my first try at longer ranges with a tactical style scope. I am looking at the Viper PST, Sightron and also the Leupolds. Was wondering what the difference is between the ER/T and the LR/T? I am looking at the 6.5-20x50. I think I want the TMR reticle and MOA adjustments. Then again I would not know the difference between MOA and MIL
