The Lee kit is a good kit for a good price. I am not sure what your budget is. For instance, I prefer the RCBS scale, and the RCBS Uniflow powder measure to the ones from LEE. That being said, the Lee equipment will get your loading Good Ammo for a good price. I do like the Lee Turret 4 die per head press real well. It would *NOT* be my first choice if you plan on heavy duty brass resizing. For instance, if you plan on using military 30-06 brass and making it into 25-06, that is rough on a press. For that I break out my RCBS Rock Chucker press. The lee turret press is nice because you can order extra heads, 1 head per setup as it were to save on Re-Setup time when you need to load up more of your favorite ammo.
One of my absolute favorite books is the Lee manual. Another favorite is the Lyman manual. Those are two of the most used books I own.
The lee of course does pitch Lee products, but I actually Like the Lee Collet dies. I would not use them for a semi-auto however! You have to actually *Gasp* Read up on how to properly set it up, or you will end up with "Collet" marks on your necks. I hear folks saying how this die sucks all the time...I usually just laugh and not bother trying to explain. It comes with instructions on how to avoid that issue
Heh. For a semi-auto you need a full length resizer anyhow, not a collet die. For your .223, I would use the Redding Type S dies with the nitride bushings:
Redding Neck Sizer Die Bushing 223 Diameter Titanium Nitride - MidwayUSA
Good shooting,

P.S. I do not personally care for the electric powder dispenser systems At ALL. Another think to note, Powder measures are so sensitive that a ceiling fan on high, or a swamp cooler, can really screw up your weights.
