Hey everyone, I am looking at a putting a FFP 4-16 Viper PST on a future elk/moose hunting rig. My question is, is it easier to range with MOA or MRAD or is it all the same as long as the reticle and turret match? Any thoughts would be helpful. Thanks. FYI, all my scopes right now have adjustment in 1/4MOA clicks, but I don't have ranging reticles or anything like that.
