No problem.
I've been learning to handload for almost 40 years,, and I've found that by getting, & using as many printed manuals as a guide to start has never caused me to damage a gun, hurt myself or anyone else. Plus,, they've often guided me easily towards the best loads I was able to assemble.
One thing often overlooked by the younger crowd that rely upon the internet, is liability. When a company publishes a book, there are implied liability issues. The data they publish has been tested,, so they have their companies covered. An internet recipe is not protected by such things.
In my little reloading corner,, I have about a dozen manuals,, all of which are the most current from each company. I also have a library of older manuals. In fact, sitting at this computer & desk, I can see 8 manuals I've shifted out of use,, and only use them for back-up reference data when my feeble mind wants to get an answer to something. (But never actual data to load into a case.)
Now,, a company that makes the powder may have data on their company website,, that can be used as a place to get good quality info. But if that's the location you use,, I'd take a picture of the page(s) and print them. Then at my bench, I'd use that info, AND save the copy. Again, they made the powder, they are publishing the data, and as such, a certain liability is attached to that. And a printed copy is proof of you using THEIR data. (They can edit their pages easily, but a printed copy is your proof, if something goes wrong.)
And even a printed manual can have mistakes. Usually when that happens,, the companies take an necessary actions to prevent accidents. Revised copies printed, publicly getting the word out in magazines & via their websites etc.
Good luck in your loading!
