Reply To: Zeroing my scope
No it will not affect the zero no matter at which magnification level you are you are using. If you check out a few of Ted’s videos on YouTube, he changes mag levels during shoots all the time.
As Dave pointed out, your mil dot readings will change as mag changes. Your scope should have specified at which mag level is the mil dot true.
True mil dot translates to about 3.6 inches @ 100 yards. You could scale it linearly.
Ex. my scope has a 20x true mil dot. So at 20x, 1 mil = 3.6 inches @ 100 yards. And at 10x, 1 mil = 7.2 inches @ 100 yards.
