I'm going to be the different fish here ,I'll get my 100 yd zero then trust my scopes BDC lines out to 625 been working great ,yes I've dialed when at the range but in a hunting situation elk at 1017 yds I hadn't enough time to dial so I let him walk , light faded along with my tag hopes ,but dats hunting . I had a Leupold 6.5x20x50 fail on me while shooting testing for my up coming elk hunt 7STW 160 partitions doing 3225 and 22 moa to reach 1000, yeah they fixed it ,repaired erector system . I lost faith went to other brands ,NF & Meopta,cheers
