If you're buying the RCBS Rock Chucker Master Reloading Kit (good choice btw) the Speer #13 Manual is included! The Lyman 48th edition is also good. Those two, along with Hodgdon's 26th are my goto manuals.
If you're a newbie, don't trust loads you find on private web sites or even manufacturer's web sites! Typos and mistakes can happen, so cross-check any and all loads you find!!!! An extra grain or two or power or a mix-up in powders and you can seriously hurt yourself. There are lots of powders on the market made by different manufacturers having the same or very similar names...they ARE NOT interchangeable!
Any new load, back off 10% from the max load listed and work up. Also, don't go under the min load either!
The ABC's of Reloading is a great book for guys new to the hobby and also includes lots of useful stuff for even the experienced reloader. Have fun and be safe!
