A little more than a month ago, I was able to shoot one of my rifles @ 600 yards for the first time. I was shooting in a stiff, gusty crosswind. The rifle I was using was chambered in 6.5x55, shooting 140g Berger VLD's, and had a Nikon Buckmasters 6-18x40 w/side parallax adjustment and mil-dot reticle. It wasn't difficult to get dialed in for the distance. I was surprised how easy it was to get dialed in for the wind. Once dialed in, my first two sighters on an F-Class target went into the ten ring. I was able to bust clay targets on the berm with ease. I was shooting fist sized five shot groups that showed very little vertical dispersion... Then the sun came out... My target began to shimmer and dance... And mirage began to give me fits. My fist sized groups became watermelon sized groups with a lot of vertical. My ten ring shots became seven ring shots. In short, the mirage kicked my newby butt. I have read a lot on this site about compensating for trajectory, wind, up/down angle, etc. However, I have seen very little information on how to deal with mirage. One thing that occurred to me after I left the range that day was that I should have turned the power down on my scope. I think that might have helped. Still, I wonder: Is it possible to dope mirage? If so, how does one read and then dope mirage? If not, what can I do to mitigate its effects? Is mirage commonly encountered in LRH situations? I would sure appreciate some advice from some of you seasoned long range hunters... "You're doin great, killer! The champ ain't laid a glove on ya." "Well keep your eye on the ref, cuz somebody's kickin' my ---!"
