If you have no knowledge of reloading get a good reloading manual first and read it.
Then try to find some one where you shoot that reloads to show you the ropes first. It will keep you from making a lot of mistakes, not just in reloading, but the better equipment you can buy that will over time save you time and money in your reloading.
Amen! I'm brand new to reloading and here's my story...
My father committed to bringing me all of his reloading equipment (nearly 50 years worth of his stuff, and it filled his entire car (all equipment probably weighed in at ~400 pounds)). But, before he brought it to me, he sent me 2 books - one on bullet casting and one on reloading and told me to read them first. I did just that, and even took lots of notes, as well as writing down all of the steps to actually cast and reload bullets. I went as far as drawing pictures of the tools I would use in each step (e.g. pocket reamers, dies, etc.).
I found that this did three things for me:
1) It piqued my interest in a huge way. At nearly 40 years old, I was getting so excited about starting to reload, I felt like a 10 year old kid on Christmas morning.
2) It tought me some of the basics of reloading in a step-by-step format and got me prepared for doing this. I kind of visualized what I needed to do in a step-by-step fashion in my mind's eye.
3) It forced me to write down lots of questions about those things I didn't understand and they ranged from "ogive" to "cannelure" and so on.
When my father did end up bringing all of his stuff, I found that I was far better prepared by reading through these manuals and our "training" sessions were MUCH, MUCH, MUCH more productive.
To Ozzieman's point, having an "expert" available is priceless. Not only was I able to learn some "old timer" tricks but more importantly, because I learned a lot of the safety items, I was able to enjoy this much more, because I wasn't worried about blowing off my hand (double charges) or ending up with a bullet stuck in my barrel (missing charge) by making a stupid mistake.
Even after ~3 months of reloading, I still call or email my father with questions and its really helpful.
As far as books go; I'd recommend the Lyman bullet casting and Lyman reloading manuals. They are well written, cover just about everything you need to know, and are written in such a way that it "tells a story" (unlike a manual that is dry and boring). At least that is this noob's opinion.
