i might get that scope. as u can see, its a 3-9×40. I was wondering do u have to re zero it for each distance i shoot at?
Example, i zero in my scope when the adjustable thing is on number “3″, i find a crow real far away then adjust it to “9″ will it be accurate, do i have to aim a little high or what?
There are two parts to your question.
First, good(but not all) scopes keep their zero no matter what magnification you dial in.
Second, you’re going to have to zero at a given range and know the ballistics of the particular load you’re shooting at other ranges, regardless of whether you leave the magnification where it is, or whether you change it. The equipment isn’t going to make up for a lack of knowledge on your part, so it’s time to start working on your homework.
