I do some reloading for 22-250, .270, 30-30 and .460 S&W. Going to get dies for .223 and .45 ACP.
Do you have your press/dies and other equipment yet? Best thing to get first is a good reloading manual. It will have a wealth of knowlege on the how to's and what not to do's.
I like to reload not only for the $ savings but it's a good way to relax and it just feels good to shoot ammo that you made.
