That wasn't my point. They don't load trying to hit a weight, they load trying for a volume based upon lot tested burning rates.
With ball powder, I'm sure you may be able to hit a pretty tight weight. Since coatings control it's burning rate, volume can get you into Pressure issues with ball powder if you have a variable VMD.
With extruded powder, the weight will always vary in a larger fashion. Since geometry is what controls it's burning rate, it's all good that there may be a difference.
