Is there such a thing here, and I just can't find it?
Has anyone scanned older manuals as PDF's?
Links to web libraries that I can't find?

I won't buy into the fact that it's more accurate at all. For one thing revolver testing isn't done with a vented barrel by SAAMI, at least it wasn't a few years ago.Old manuals would be interesting to look at. I have a couple from the 1970's, one is a first edition Speer #10, 1979 I think. I have a couple other oldies that are kind of generic, "The Basics of Handloading" and some early Mec data.
SAAMI used to measure pressures in copper crusher units of pressure, or cup. Todays more modern, and far more accurate method is by use of an electronic transducer, which determines chamber pressures in pounds per square inch, or PSI. It was the introduction of the transducer that accounts for much of the data changes that took place during that transition period. I also think much of the powder and projectile industry was greatly influenced by this precision method of measuring pressures, allowing for more advanced bullet designs.
