How do I fix this spread??!!

Hello guys I was simply testing some Metal slug style mechanics when I found this problem I cant solve, is driving me crazy.

I need the weapon to shoot the bullet with a spread effect. To achieve that i told C2 to:

set bullet angle of motion to > gun angle +random(-5,5).

When the gun angle is 0 it works prefectly in any other direction i shoots straight with no spread <img src="{SMILIES_PATH}/icon_evil.gif" alt=":evil:" title="Evil or Very Mad">

Here is a capx: https://www.copy.com/s/QhVnW3oQd7cr/Spread%20fail.capx

Hope someone finds the problem.

For some reason it was to do with the "set angle of motion" action. I used "set angle" (in the angle subsection of the object) and it worked perfectly.

Sumyjkl thanks to you I found the problem. I had to set "Set Angle" to NO in the bullet properties.
