Welcome to reloading! It will take your shooting and hunting experiences to a whole new level. It is fun to play with loads and find out what your gun likes. And, most of the time, you can load up something that will out shoot any factory load, and at a significant cost savings!
I have the RCBS Rock Chucker kit that I purchased 12 years ago (I'm 26 now, so I was your age when I started!) I started loading for my .280, then my .22-250, then .223, and so on. By the way, you won't save any money reloading, if anything, it will cost you a lot more! You shoot way more than before. That's how it worked for me. I figured I was saving a bunch of money, so I could shoot more, and boy did I ever. It was the best thing I ever did as far as shooting goes. My shooting abilities increased 10 fold!
Here are a few things that I have picked up over the small time I've been doing this that have helped me.
-Use spray on case lube (One Shot from Hornady). It is a lot cleaner than the RCBS lube and pad. And I think it is more consistent too.
-Hand Priming tool (Either RCBS or Hornady). You can get a better "feel" for how the primer seats. Also, you can watch tv, prime, and still spend time with the misses! (This is a very valuable lesson, keep the little woman happy, and you can have more toys, and be able to use them if you're lucky!)
-Electronic Scale & Dispenser Combo. I have the RCBS and I love it. I don't have to trickle and weigh every charge, and it is very accurate. Downside is the price.
-Tumbler. Comes in very handy. Other wise you can soak cases in a mixture of hot water and dish soap. This cleans the cases pretty good. Also, you won't have any dirt get caught in your die and causing a stuck case!
-Stuck Case Remover. This has only happened once, and I didn't not have a remover, a few days before a mule deer hunt in Wyoming. I learned my lesson.
Also, if you can, buy cases, bullets, and primers in bulk. It may be more money up front, but it will save you in the long run. For .22 cal, I have shot Sierra and Hornady with great results, and good pricing. My .223 and .22-250 really like the 52 gr Sierra Matchkings.
These are a few tools that have helped me. You can get by just fine with out them, but they are nice to have! I picked up things here and there over the years. Anyway, happy shooting and good luck!
