Buy several manuals. Read them cover to cover several times. Then go buy some equipment if you still want to load.
You will not be able to load ammo that is better in your gun than at least one of the factory loads unless you do it carefully, scientifically, and safely, and you won't load better ammo than the factories unless you test all your ammo carefully, scientifically, and safely. Keep records. Record keeping is a vital part of the scientific aspect of reloading and will teach you a lot as your records grow.

Reloading is a science - shooting is an art. Unless you are truly interested in the science of internal, external, and terminal ballistics, your reloading will likely not produce superior ammunition. Because it takes so much shooting to do the testing and experimenting necessary to scientifically draw conclusions about the effectiveness of particular loads, reloading good ammo is not cheaper than buying factory made. You can make cheap ammo, but it will only be cheap, not good; so do not expect to save money.
If you work at it, it is very likely you will be able to make very good ammo that does exactly what you want in your guns. It's also fascinating.
