Also, if you have time, do a case water overflow capacity measurement.
How about if I filled a primed case to the brim full of N135, and did it for 5 or so cases, then measured what was held in a case. Particularly as a primed case is also clean on the inside.
Between the average weight of those full case loads and the density of the powder, would that not also give you similar values for internal volume, or is water that much more accurate?
You cannot wake someone who is pretending to sleep. Stop pretending. Wake up.
Doubt: ...it's the only thing I'm sure of...
