I just sent a HDMR back to Midway a couple days ago and ordered another NF high speed with zero stop. I loved the Bushy and ran it for a couple months on a 7 mag but last week after dialing out for the 1300 yard steel then back to 700, and down for another 100 yard group it did not come back to zero. It was 2.5 mils high on the hundred yard line so I rezeroed and reapeted the above. Again for the second go around it did not return to zero this time almost a full 3 mils low. It was in a Larue LT120 all snugged to spec with both levers locked. After trying some more it was only getting worse and I was done messing with it. This is the first time in ten years I have ever ventured from Nightforce and It will not happen again. Midway and Euro have NF on sell now from 1200 to 1499 depending on the model. I have never had any issues with NF of any type maybe Ive been lucky and on the same note maybe just unlucky on my first Bushy. My Brother runs the same Bushy I had troubles with on a Win Mag with zero issues so it was probaly just a bad egg.
