Right.
There are two methods.

1. If you are a good consistent shot, then set up a target (with a small bullseye), and stand at the distance away from the target that you will be shooting normally (around 20meters is fine). Take 10 shots at the bullseye, and see what the grouping of your shots is. From here, unscrew the caps on the top and side of the scope, and adjust the dials. Read on your scope or the scope intructions how many clicks (literally one click as you move the dial)it takes to adjust the scope; usually around '1 click for 1/4 of an inch at 100 meters'. Play around with it, but only adjust about 3 clicks at a time. Every time you do, take 10 shots to see how it has changed.

2. Exactly as above, but put your gun in a solid clamp, and fire from there. It shoud be more accurate.

If this doesn't make sense (which it probably doesn't), ask a shooting friend to show you.
Good luck!

- I allmost forgot- put your scope on MAXIMUM magnification, as this will be more accurate.

cheers, ill try it tommorow.
