35 or 40 years ago I had some for several cartridges and bought the full set of plastic powder dippers and the Lee book with data from the powder companies, since the Internet wasn't public back then.
Some shops had load guides you could view without buying the whole book.
I would get data from Hornady and Sierra in those.
Later an RCBS 502 powder scale to check the dippers.
They were purposely light, to be, safe, mid loads, with the powders recommended.
Later Lee started selling real sizing dies and presses and no long after, came out with a hand press that worked more smoothly than Lyman's.
Then I got a bench mounted press and an RCBS 505 scale.
The 505 scale seemed slightly nicer than the 502 scale, but the results were the same and I would have been happy with the 502.
Lee came out with a hand priming tool, that wasn't as nice as the current one, but much cheaper than RCBS at the time.
