I get what you are saying, but no idea why it is that way.
While trying to work around the lack of powder, something I noticed in rifle loads is sometimes powders are listed for a given cartridge, but not for a nearly identical cartridge. Another thing I have with various parent/child cases, some will use the same powder, but one case(no rhyme or reason on parent or necked up/down) may not.
1 company's loads may be close to all the others, but they may be the only 1 to use a certain powder.
