Reloading 101: Reloading basics for the new reload - Sniper's Hide Forums
I would get a good single stage press and work from there (good set of calipers, headspace gauge, primer pocket tools, chamfer tools, trimmer, die set, and very important:reloading manual such as Lyman or Nosler -these will really give you a solid foundation, then when you think you know it, keep reading more and more and more and more).
Dont worry about powder, primers or bullet components right now, but learn the ins/outs of case prep. for each of those calibers and practice doing a bunch. Keep reading up, you will find there is no 'ONE' way to do it, but will learn what works best for you and your gun(s) have fun..
