Yes the filler will effect your pressure. The easiest way I can describe it is, the filler becomes a projectile as well (doesn't have anywhere to go except down the tube). You are adding to the mass of your bullet, by a LOT. I use the corn meal to fire form 6.5-06AI brass & it works really well, but this is done w/o a bullet.
Be extremely careful with this experiment, there is a gent here locally who decided to use corn meal to increase the consistency of his target rifle's full tilt loads. He now only has one eye & no thumb after his rifle grenaded on him.
Be very careful, I just can't advise doing that....
