The powder measures measure "grain equivalent". some where back in the past some one poured a weighed grain of powder into a container and said that is a grain equivalent. That volume has remained the same since. If you have a selection of powder measurers, it is unlikely that they will all measure exactly the same. I have 5 and there is 2 or 3 gr equivalent units difference between them.
Don't make no never mind. Call it what you like, just load the same volume for Pyrodex as you do for real black.
