Hi Corey - you are on the right track. If cost is a factor and you want a challenging learning experience, there is no need to go high-tech.
Yes, the four die sets work great. I started on a single-stage RCBS, and went to a Lee Classic Cast turret and am happy with it for speed. Like you and others say, turrets are so easy to change, so setting up for a different caliber only takes a moment. I did grind the stops from the linkage so it follows through and overcentres - I prefer that.
Lee's primer feeder is crappy - some use it, but I just pick up primers from the bench and load the arm.
Use Lee shell holders - others cause some problems with the Lee press - flipped and sideways primers caused by the little guide sleeve on the primer arm getting snagged on machining marks on the inside of the shell holder primer hole.
The disc type powder measure is fine - go to Canadian Tire and get new much-longer brass machine screws that fit the nice brass nuts that come with the measure and then you don't need to take the nuts off when you change discs - just loosen them.
It sounds like you have read up some - great. Have you decided on a pistol powder yet? I've tried these ones:
Hodgdon Universal - not very consistent velocities at ACP pressures.
Hodgdon Clays is a very consistent powder for 45 acp ( sorry I haven't loaded 9 mm,) and measures accurately - my favourite accuracy powder.
Hodgdon Longshot is slower burning and needs more barrel to burn in
Hodgdon Titegroup is a good target powder - a little goes a long way.
Hodgdon Lil Gun - slow burning - for your 454 when you get it
Hodgdon HP38 - not a favorite of mine - it seems to have powder dust in with the larger grains of powder.
Alliant 2400 - for your 454 long barrel too.
Aliant Bullseye - Bullseye is great, but maybe wait until you are proficient with your stuff as Bullseye is very compact and allows you to double-charge without noticing.
Check your reloading manual and you will notice that some powders need much heavier charges so a pound of powder won't go near as far - and notice that lots of cans of powder are not a full pound either.
Remington primers are the only ones I would shy away from - they don't seem to be large enough to stick in an oft-reloaded case.
Magnum primers will give a little more pressure so back the powder down a notch if you use them.
Your .223 will be very efficient of powder compared to larger cased calibers shooting the same weight of bullet the same speed.
A double-disc kit might allow you to use your pistol measure to powder your .223. Another way is to double-cycle a single disc and weigh your charge.
Your big cost for reloading will be your leads - Rainier copper plated work fine but cost adds up - even lubed cast bullets cost far more than your powder and primers. Reloading will cut your cost in half I think but casting your own bullets will bring your cost way down - less than 2.00 a box for my .45.
A heavy bullet may cycle your action better at lower target velocities.
A flattish point on a bullet leaves a little nicer hole in the paper target.
If you load cast, keep checking for lead and learn how to remove it.
Midway has the classic cast turret on sale right now - 77 bucks. This might get you there.
