Count on that being 32.5 up and 32.5 down, so you'd be able to dial in 32.5 MOA of drop in that scope.
A .308 Win with 175gr SMK moving 2600fps, 100 yard zero, will have a drop of 221 inches at 800 yards.
At 800 yards roughly 8" = 1 MOA. 221/8 = 27.625 MOA. At this distance, your scope would probably make it, but that's a maybe. Only way to find out is to have Bubba shoot it. :))
At that distance, don't make it a rough estimate, though. 1 MOA = 1.047" at 100 yards. 1 MOA = 8.376" at 800 yards. 221/8.376 = 26.385 MOA of drop at 800 yards.
If you needed 26.385 MOA of drop to hit your target at 800 yards, and you dialed in 27.625 MOA of drop, that's enough of a difference in bullet impact to be a miss and not a hit. Probably about a 10 inch difference at that distance.
Lesson? Buy a ballistic calculator, download a ballistic calculator app for your phone, or take paper, pencil and calculator to the range with you... <thumbsup>
