Usually when someone asks me about embarking on the addiction and/or affliction of handloading I steer them towards manuals such as Lyman's 49th. After the last few weeks I have had cause to reexamine what I use as my initial recommendation for a manual. Like many I started loading on a work bench in my garage. Soon I learned that I needed a dedicated loading bench. Knowing that I probably couldn't buy anything that I really wanted I resolved to build my bench. This lead to a search for what I thought I needed and I built the biggesdt, badest, most tricked out bench I could find. This worked for awhile but then I needed more room for more stuff and built another bench/benches. This helped greatly but then like everything else I wanted more. Fast forward to today and I am now about halfway through a winter long remodel project in my entire garage! This will be very nice when I'm done but I now wonder how long it will be before I am adding on to my garage for even more room and subsequent loading benches!
Therefore, my first recommendation for anyone starting out handloading will be a book on carpentry. Once the basic skills of carpentry are firmly seated then, and only then, should anyone proceed with learning the finer aspects of assembling ammunition. This would probably be a good book to start with.
