I started with .308 and .357 using a single stage RCBS, worked great but to improve speed a bit i bought a Redding Turret as well. I'm sure the Lee would be fine as well, pretty simple process to reload once you do it a few times. I have a number of reloading books such as Lyman, Hornady, Speer, etc. but found the best info for me was watching many many you tubes on what I was wanting to reload, some are excellent.
Important things are a good powder scale, calipers, good die sets, brass prep equipment, and most important is patience and caution. Double and triple check everything to start, always start with starting powder charges, go slow at first, after awhile you will become proficient. I'm no expert but have now safely loaded thousands of .357, .308, and .44's
