I have a Savage stevens 200 with Lothar walthar 26" stainless heavy barrel. and X10 SS SWFA scope.

I have always reloaded for all my rifles and handguns. This situation is a first for me ;;

I am using Vectan powders Tubal 5000 / Winchester Large rifle primers / Winchester brass cases / and 150gr psp bullets.
As on the load data I have (from a trusted book I always use) it states min load 2.65g and max 2.70g. I have reloaded 20 at 2.65g. When the bullet is seated to the crimp mark on the bullet , I noticed the powder fills the case up to the case neck and by shaking it next to my ear, it is obvious that there is extremely little or no air between the bullet and the powder. This seems odd to me, as every load I have ever done before for my other caliber rifles, you can see there is at least 25% of the bullet that is empty of powder.
Is this normal ??
