Since my manuals are old, sometimes when a new caliber comes along, none of my manuals have any information for it. This happened to me many moons ago when I won a .480 Ruger at a Friends of NRA banquet. I discovered there was a lot of load data available free over the Internet. Particularly from powder makers. If I was new to reloading and wasn't sure it was something I would be doing a lot of, or for only one or two calibers, I would see how much information I could glean from the Internet first. And by that I mean from reputable industry sources, NOT some random guy on a forum telling you to use XXX grains of XXX powder "and don't worry about the primers popping out".
In my case, I've collected several manuals because I've got a couple dozen sets of dies for different calibers. Only a couple of which I don't have a gun for - YET.
