Damage Oddities with projectiles

I am having some problems with my projectile damage and I can't seem to figure out the cause.

First, I should mention that damage is set up a little differently for my weapons. The player actually carries the weapons damage value(it's user defined), and it's passed in the projectiles onCollision function.

If I fire my weapon and hit a target at long rage, no damage is done. And strangly enough, the projectiles "sourceObject" becomes invalid as well(which is bad). But at close range, everything is fine and the sourceObject stays valid. You would think this might be due to the projectile fading before it hit it's target, but it isn't. It even makes it's collision effect.

There is a fix I found, but it doesn't yield the result I am looking for. Basically I just increase the ProjectileData's muzzleVelocity and it works great at any distance. Well, aside from the fact that my flame throwers and gas sprayers now shoot at the speed of a bullet. So this indicates that it is either a range or a time issue.

If I can figure out how to keep sourceObject valid, I am sure I could fix my overall problem.

Here is the solid based projectile:

datablock ProjectileData(SolidProjectile){
   projectileShapeName = "~/data/shapes/Gun/SolidProj.dts";
   directDamage        = 0;
   radiusDamage        = 0; //10;
   damageRadius        = 0; //0.5;
   //explosion           = DefaultExplosion;
   //particleEmitter     = DefaultTrailEmitter;

   muzzleVelocity      = 1000; // RANGE???
   velInheritFactor    = 1;

   armingDelay         = 0;
   lifetime            = 10000;
   fadeDelay           = 10000;
   bounceElasticity    = 0;
   bounceFriction      = 0;
   isBallistic         = true;
   gravityMod = 0.10;

   hasLight    = false;
   lightRadius = 1.0;
   lightColor  = "0 0 0.0";
};

datablock ProjectileData(SolidBallistic : SolidProjectile){
	explosion           = SolidRicochet;
};

function SolidBallistic::onCollision(%this,%obj,%col,%fade,%pos,%normal)
{
   // Apply damage to the object all shape base objects
   %damage = %obj.sourceObject.DamageValue; // becomes invalid at longer ranges
	
   if (%col.getType() & $TypeMasks::ShapeBaseObjectType)
      %col.damage(%obj,%pos,%damage,"BallisticBase");

   // Radius damage is a support scripts defined in radiusDamage.cs
   //radiusDamage(%obj,%pos,%this.damageRadius,%damage,"BallisticBase",0);
}

I have been racking my brain on this for a while. Any help would be great!

Thanks,
