use march 1 -10 x 24,with mml reticle very unfussy, use 21 yards setting at x8 which gives me best between 8- 45 yrds ,very clear 17-27 yrds which i use to range find, and a bit fussy at 15 and 35 use to range , its very expensive,but after using many scopes got fed up swopping found this to be a great scope super glass which is what you are paying for,if you get the chance to check one out do so you will see what i mean happy shooting
