Read what I said again, Richard. I'm talking about the power grid, not your house power, and your smart phone would be useless, as would every other electronic gadget in such an event. Nothing is forever that is powered by electricity. Paper is real, and the reality is manuals are necessary for reference, no matter the situation.
I've experienced extended power outages that have lasted for up to a week or more, and it makes one really realize how dependent we've become on the power grid. I'm not a "doomsdayer" or "preppy", but I'm intelligent enough to know that with the power gone for an extended period of time, then we're back in the 1880's very shortly. I would suggest you read the book, "One Second After", for a glimpse at what it would possibly be like if we were hit with an EMP, either manmade or natural.
I was an adult in the 1960's, when the domestic terrorists were bombing electrical transmission lines, buildings and other infrastructure, and later on went into Law Enforcement, where I retired as a manager of a department with over 1,000 employees. I know how vulnerable our whole system of life is, and if you don't realize it now, you will quickly if it ever happens to you. It doesn't take more than a couple of disasters to see how fragile our whole system is. That's reality, not the "cloud" where everything else is stored.
Enough of that small rant, and back on topic. Reloading manuals represent huge amounts of labor and time to produce. Some, like Lee's, just copy the work of others, but the bullet and powder companies expend huge amounts of resources in doing the research necessary to publish the data we now have. Like I said in a previous post, it hasn't always been that way. I've been in the ballistics labs of both Nosler (twice) and Sierra. Both of those companies have made huge investments in testing equipment, range tunnels, pressure barrels, etc., to say nothing of the man hours and trained ballisticians. Extrapolate that out over all the other companies and you may get an idea of the investment they've all made, and you expect them to provide it to you free gratis. Of course, those costs are built into the price of their products somewhat, but I say it again, it's amazing that they produce the manuals they do for the small costs they charge for them.
Hope this helps.
