But to be honest you can find all the same data for yourself if you look around. The most reliable load data comes from the manufacturer of the powder used, and all the powder makers have load data on their websites these days.
In that respect you might say the best load manual is a combination of google and an inexpensive chronometer. There are a lot of things to buy as a beginning reloader, but I see the chronometer second to only the powder scale and calipers in terms of safety impact.
I fully agree with the first paragraph above, but the following one I have issues with.
If what you posted is true and had been repeated all over the net and in books, I wouldn't have been able to start reloading when I did for as little as I did. If one, starts with known reliable load data at the start value, doesn't exceed the published max values and watches for signs of high pressure a chrono isn't necessary.
IMHO a beginning reloader, is learning so many things, that messing with a chrono isn't another thing they need to do. The top priority is to make safe, reliable loads and to learn good practices. This can be done by starting low, and working up loads carefully but not exceeding max published. It's why so many suggest multiple manuals. By having multiple manuals, a loaded can decide what a safe max is. In my case, when I started I chose the lowest value. Now that I have more experience, and I know my guns better, I feel safer looking at an average, but I'll still throw up a value if it is much higher than the others. And I still look closely for high pressure signals.
So OP has enough to buy and learn. If a chrono is something they can afford right now, great but saying it's needed for safety is wrong. Many loaders don't use them and make safe loads. Many have decades of experience. Now don't get me wrong, I don't have decades of experience, and I really want a chrono, but it's not a priority right now. And I'm making safe loads following safe practices used by those who have done this for decades.
Again, OP needs a good book like Lee to read for all of the skills, they need another to have for a comparison. Powder companies have load books they give away, and their websites list load data for their powders. So that's a lot for them now. I say, they get their gear and books together. Read all they can in the mean time, then when ready load some rounds on the lower end to middle of the load data and go to the range. That first round fired will be special for them. The rest will be cool.
From there they can get confidence, learn safe loading and then worry about making rounds that need a chrono.
