BTW, when looking for what would be a "full case" of powder, i found out early on that what appears in the manuals and what happens inside your individual case using your powder lot and your bullet seating depth.....are two different things. First clue was when I tried weighing the amount of powder I got from the Lee dippers vs. what is shown in tables for same. Some powders were similar.....most were not even close.
So what I came up with was a device of my own creation...........I would take a sized, ready to load empty case, seat the bullet in question to whatever OAL i would be using........then drilled out the primer cup such that I was able to backfill the case under the seated bullet until case was filled to overflowing. Then weigh that and I have weight of a 100% full case. I do that for every powder I try......at least for all the rifle calibers I'm loading for.
Have not done that for pistols, but beginning to think it may be a good idea, as it will give me some idea as to what a full to compressed powder charge would be. It could be that out of the dozens and dozens of powders used in 9mm, a best one might be one that gives you a full to lightly compressed powder charge at the seating depth used........dictated by choice or max OAL.
