A little blinded by science, this end!!
I can understand things much better seeing them in action, rather than looking at abstract numbers, but I found this chart for .308 (Table 1)
Taking the row showing a zero'ed scope at 100 yards, thus matching the data on the Burris scope page, the bullet drop at 1000yds is 421".
This means 42.1 MOA. According to what you've confirmed about the up/down adjustment being 45 MOA either way, I should have enough adjustment in the scope to make a 1000yds shot theoretically possible using that scope and a .308 round.... I think....
Am I on the right page here?
