I'm considering a Dillon 650 to start reloading, again. I haven't reloaded in about 12 years. My question is, what size dies should I buy with my initial set up. I plan to reload 9mm, 40 S&W, & 45ACP. I want to get the most bang for my buck, so considering lead, brass, primers etc. which cal. would you recommend starting with? Also what is a good, clean powder to use? Reasonably priced place to buy brass, primers, bullets etc.? Sorry for the remedial questions but after being out of the loop for so long, much has been forgotten. Back when I used to reload I had a 550B, but always wanted the big brother, I think it's time to take the plunge. Thanks in advance.
