Re: What kind of reloader are you using?
For rifle rounds, a single stage is fine. If you are going to reload pistol rounds you want a progressive. I reload on an RCBS Pro 2000, and have a manual head and a self-indexing head for it. I reload over a dozen different calibers on it; bulk pistol ammo for USPSA shooting, long distance rifle ammo, bulk AR ammo, and hunting ammo.
With that said, I've played with or used most of the reloaders on the market today and recommend the Dillon 550 as a first reloader across the board. It will do anything you want, flexible enough to change calibers, accurate enough for long distance rounds, simple enought to learn on, and is rock solid with a no BS warranty. You can't go wrong with it, and even if you absolutely hate it, it will sell immediately on any of the shooting blog sites.
