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.
Yep, love the Nikon's. Have a pair of Pro Staff 5 Binoculars and a Buckmaster 4.5-14. I've also owned the Buckmaster 6-18 with target dot. Worked well to see groundhogs to 1000yrds. Depending on caliber, you may run out of elevation adjustment if you don't use a 20MOA base with the Buckmaster models.
