I got a new 10-50x60 LRMOA-2 yesterday and mounted it up. When I got to the range today I was having problems getting zero at 100. I didn't have enough travel to get a 100 yard zero with my 20 moa base. When the scope was near the bottom of the elevation travel, it would not move left or right. When it was totally bottomed out on the elevation adjustment the first 15-20 clicks walked up and to the right. After that it seemed to track up and down correctly and would adjust left and right again. Do they all do this or should I send it back?
