First: I’m in no hurry. If it takes a few more minutes that’s fine.
Next: if a load is published, even if it’s from 1998 or 1975, it should be a good load? I don’t load maximum powder charge for fun/target shooting and I generally will hunt with factory for now.
So: if I weigh every load, the “how to measure” question is moot since I’m ultimately going by weight, right? I might start with a volume measure, but every charge will go on the scale.
(Sub question: “magnum” primers can be used in place of non-magnum primers by decreasing the powder charge by a grain?)
Dad gave me a bunch of powder and primers.
