Yes, i agree. What i have always done over the years i have been burning Blackhorn, is keep the weight constant for a given load, even when opening a new bottle from a different lot. This means the volume 'inevitably' changed. Whenever i loaded my rifle with 110g Blackhorn, the powder always weighed 77g, but the actual volume, was really unknown.

Myself, i always felt if the weight from lot to lot was kept the same, the velocity would also be kept the same or nearly so. Of course, the velocity probably isn't exactly the same from lot to lot, even when maintaining the same weight. To me, holding the weight is more important, than holding the volume.
It very well may be, i am totally wrong.
Over the years of hunting, shooting, reloading, shooting, reloading, hunting, right or wrong, we always tried to sight our rifles in for hunting using all components from the same lot. Perhaps it was anal, but we purchased enough bullets, and made sure they they were from the same lot, so we used them same bullets for sighting in and for hunting. The same thing was done with primers, powder, and brass.

Yup, i agree.
