One of the worst things I don't do right is neck tension and case tension of straight walled cases. There's also videos I've watched about expanding such cases and this is one that's a bit of difficulty. That is adjusting for minimal brass working and such. Then there's these terms like "bumping a shoulder" and it seems some chambers are not within spec. Lots of issues that can come up and some terms are difficult to find in print. Fact is some terms are actually not correct yet widely used so that's an added bunch of jargon
