I have a 6-18 Buckmaster on my Savage .22-250 SS FV. I've shot it out to 850 yards at targets. It seems to be clear, adjustments are accurate, and has been repeatable over and over. I also have one one a Savage .243 model 10 hunting rifle that mimics the first one. I like the glass almost as good as my Leupold VXIII.
