All Ammo damages reduced by 3

Hello

For all people who feel that the blocks are in paper here is another of my armors / ammo tweak :

- Huge decrease on hand riffle ammo : max 600 range and around /5 damages
- Medium decrease of heavy ammos / missiles by 3

Note : this mod ***** be removed any time, it's only a change in "ammos" file.

Also any other mod with custom weapons will brake this if its not loaded before this one (and so this one ***** delete others weapons datas)
