Need some assistance

[benchrester83]

I just bought a vortex HS 4x16x44 scope for my lr308 and am having some trouble.

Can anyone explain to me what a MOA is?
Also, if I am consistently shooting 3-4 inches to the left of my target at 100 yards, what knob do I turn to get it in line with my crosshairs?
If anyone can help out with some advice or a link that explains some of this stuff a little better than the instruction booklet for the scope it would be greatly appreciated.

"MOA" is the abbreviation for minute of angle. For our needs as shooters, it works out, mathematically, to 1 inch at 100 yards for your and - as you might expect - increases in multiples of 1 additional inch for every additional 100 yards. 2" at 200 yds, 5" at 500 yds, etc.
The "knob" you need to turn is the one on the right side of the scope. It will have "R" and "L" printed on it. Turn it in the direction (R or L) you want the group to move.

Appears you're new to scope sights. Here's some reading that may help you:
