I have the Speer #9 manual (copyright 1974, the one right after the OP's) and it doesn't list H110 (aka WW 296, even back then) loads for any weight 9 mm bullet, jacketed or lead. Of the powders both #8 and #9 mention, Bullseye, Red Dot, Green Dot, Blue Dot (#9 only), Unique, H110, and 700X are the ones I know that are still available.
WW230 was renamed WW231 sometime later. I don't know if it's exactly the same powder but the published loads in #8 for the 125 gr soft point seem hot while the loads in #9 are the same as still published current for WW 231.
One reason that modern manuals appear to have reduced the maximum powder charges for most bullet/powder combinations is that the powder and bullet makers began to get real pressure testing equipment about the early-to-mid-70's and developed true pressure data, not estimates based on primer appearance, etc. At first they used lead or copper crushers and, more recently, piezo electric pressure transducers. Both gave objective readings, not guesses.
