Found a mod that adds the the Fallout 2 Wattz lasers to FO3. The author gave up on it because he as unable to get the Wattz 2000 Ext Cap rifle to work right.

Ammo : MF Cell
Clip size : 48 (Wanted)

Using the GECK to change the clip size in the rifle does weird things to ammo consumption rates.
Clip size shows as 48 but you use one cell per shot ?!?

Then there is an entry in Levelling Items for ClipLaserRifle30. How does that fit in?

Under AmmoMicroFusionCell it states every cell has 20 shots?

Is there some weird ( built in / compiled in ) formula in the binary that is effecting this?

Tried creating a new ammo type and switched the rifle over to it. Still got very strange ammo consumption rates.

Comments and/or Instruction very welcome.
And yes, if it can be fixed the mod author will need to update his download site ...
