In the U.S. internet etiquette, everything capitalized or bolded is generally the equivalent of "yelling"... no need to yell.

How are things in Saudi Arabia?

You left out a lot of critical information...  caliber, ammo you are using, target size, typical environmental conditions...

provide details on what it is you are shooting, what you are shooting at... you can possibly find help here.


Welcome to OT.

The most important data needed is bullet weight and bullet speed.

Thank you for your nice replay 
I thought 8 clicks = 100m
Is there any mathematical calculation for this to increase the accuracy?

rightsa,
Each rifle is shoots the same ammo differently due to many factors. In order to be very precise you need to shoot the bullet through a chronograph to get the exact speed of the bullet.
 
So assuming your data is correct and assuming your scope dials 1/4MOA per click (this you will have to check)
From 350 to 300 meters = 1.7MOA x 4 = 6.8 clicks.
To go to 250 meters = 3.2MOA x4 = 12,8 clicks
All will be down clicks as you are zeroed at 350m
 
To get to 100m = 6.1MOA x4 = 24.4 clicks.
 
And so on.
 
Mostly we zero at 100m and dial up. So to get from 100m zero to 350m would be 24.4 clicks up

OK, I did not research your scope, so you would have to dial as follows:
 
1.7 x 8 clicks = 13.6 clicks.
 
You stated that you have zeroed the rifle/scope at 350m. So you then wanted to know how many clicks to hit a 300m target. From 350m zero back to 300m is 1.7MOA
 
I assume you have actually fired at a 350m target and hit it???
 
So dial DOWN 13 or 14 clicks and you should be close to hitting your 300m target.
