[Trigger] bullet not spawning correct place?

[Diehard@Azeroth]

I have a really annoying problem here... i used x and y intercepts and some math to calculate a bullets movement, anyhow, the spawning place of the bullet can sometimes be in the casters x and y intercept location and sometimes it spawns to the left of the caster and goes to the angle from there. Can anyone tell me why? the bullet does have locust (collision off) and spawns in the casters x and y intercept.
Here is the trigger:

• ShootingStart
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
    • (Ability being cast) Equal to Sniper Shot
  • Actions
    • Custom script: local unit u = GetTriggerUnit()
    • Custom script: local real x = GetUnitX(u)
    • Custom script: local real y = GetUnitY(u)
    • Custom script: local location t = GetSpellTargetLoc()
    • Custom script: local real distX = GetLocationX(t) - x
    • Custom script: local real distY = GetLocationY(t) - y
    • Custom script: local real dist = SquareRoot(distX*distX + distY*distY)
    • Custom script: local real dx = distX/dist*udg_BulletSpeed*udg_Time
    • Custom script: local real dy = distY/dist*udg_BulletSpeed*udg_Time
    • Custom script: local real angle = bj_RADTODEG*Atan2(distY, distX)
    • Custom script: call RemoveLocation(t)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • i Less than 8192
      • Then - Actions
        • Set i = (i + 1)
      • Else - Actions
        • Set i = 0
        • Set i = (i + 1)
    • Custom script: set udg_Bullet[udg_i] = CreateUnit(GetOwningPlayer(u), 'e000', x, y, angle)
    • Custom script: call AddFlying(udg_Bullet[udg_i])
    • Custom script: set udg_BulletMoveX[udg_i] = dx
    • Custom script: set udg_BulletMoveY[udg_i] = dy
    • Unit - Set the custom value of Bullet[i] to i
    • Set Bullet_Dist[i] = Bullet_Max_Dist
    • Unit Group - Add Bullet[i] to BulletGroup
    • Trigger - Turn on MovingBullet <gen>

Why would you put this all as Custom Script? It'd be simpler if you put it in JASS.
