I haven't yet gotten to swhoot my 7mm mag with a 4.5x14 fullfield II, I understand the focus (where you look through you can turn it and it focuses in and out), and the moa clickers but there is a adjustment on the front lense marked 50 yds, 100yds, 200, 300, 400, OO

obviously they are yardages but what purpose do they serve when you rotate it to the coresponding yardage? does it focus it, does it range find for you? I dont understand the purpose

APPRECIATE ANY HELP

Its parallax adjustment...

You'll like the scope. I really like mine on my .300 Win Mag, and it came with a 12-24x spotting scope too.

yeah... I like it already and I havent even shot it yet... but I think I will be selling that stupid spotting scope since I can get to use one at the range for free and well.. I need a range finder lol
