Somewhere around line 190 is this block of text :
Code:
RateOfFire = 1050
   ReloadTime = 1150
   FullAuto = 1
   FireIgnoresThis = 1
   ShakeRange = 8
   SharpShakeRange = 5
   NoSupportFactor = 1.4
   ParticleSpreadRange = 1.5
   ShellSpreadRange = 8
   ShellAngVelRange = 2
Now lets say you want to change the spread, You need to change the ParticleSpreadRange ( If I remember correct)
To make it shoot accurate, you need to make it like this :
Code:
RateOfFire = 1050
   ReloadTime = 1150
   FullAuto = 1
   FireIgnoresThis = 1
   ShakeRange = 8
   SharpShakeRange = 5
   NoSupportFactor = 1.4
   ParticleSpreadRange = 0.5
   ShellSpreadRange = 8
   ShellAngVelRange = 2
