It's been a while since I loaded any cases up, but the last ones I did were .308 on my rockchucker-II one die at a time.
I went round and round and settled on a fairly simple formula that worked well for me, and in hind sight, would be quite inexpensive.
The rockchucker I had. Find them used or new- the investment is one-time on this. Lee seems fine, and less expensive, but whatever you get, go cast iron, not welded steel or aluminum. (I have no idea what is "hot" these days)
Get a good quality neck sizing collet die. I think mine is a Forester... I don't remember but what ever it is, it should be adjustable. That accounts for wear, and you can make it perfect for your needs. A full length sizer if you have brand new brass or brass not fired in the rifle you are loading for.
So, this all requires a good measurement device. Consistency=accuracy, and vice versa. Don't get a harbor freight caliper. Spend the (less than a case of ammo cost) for a decent caliper. I have had good luck (for decades) with Mitutoyo. But there are other brands that are fine as well. Spend what you are comfortable with, but if you can't find the country of origin on a map- avoid it. A zero reset is nice but since you are logging everything you do for each load in your log book, start dimensions are not a big deal to note as well...
I use the RCBS adjustable powder 'dump' set a little light and then top up with a trickler onto a triple-beam RCBS balance. Yes, it's tedious but Consistency=accuracy. At the time digital stuff was not repeatable enough. Maybe it's better now, and I expect anything "good" is going to be expensive. And I always re-zero the balance every 20 or so rounds, and reset it to my target weight. (don't move the balance once set either) Yes, it's a bit of "wasted" time but Consistency=accuracy.
Hand seat your primers. You need to feel that.
Fire form cases to the rifle. If you have several of the same caliber you are going to work up a load for each rifle anyway, so you may consider different brands of brass for each rifle, to make sorting easier. Or you can mark the bases with color- model paint, nail polish whatever gets into the stampings on the base and it is easier to segregate them.
Uniform the primer pockets and flash holes of all cases. Even brand new ones. (you should only need to do this once!)
I full length size brand new cases and then set OAL to print maximum before the first loading. I have a manual case length trimmer (not sure of brand now- it's packed away) and after fire-forming, I checked length on every case and trim anything over max OAL (back to max OAL).
With the (Hornady match) bullets I was using, I was not close to the lands, so I made my cartridges at max OAL with the bullet seated. This allowed them to function in the (R700) magazine with no issues. It also allowed the case to lightly grab the bullets. On that note, I had a very "weak" grab on my bullets because I went from loading bench to shooting bench with not much in between. Cartridges were stored bullet up in some nice plastic cases I got from Cabelas that kept them standing up and protected. If you do a hunting round, you must crimp the bullet well so it does not fall out or get knocked out of line. If you manually chamber one round at a time, you may be able to go longer if your bullet allows it and you are not too close to the lands with the ogive. That's a bit tricky to measure accurately but there are "old school" methods that work well and are basically free.
For cleaning I used walnut shells and a couple drops of "Nu Finish". I would run strips of white paper towel once in a while in the media (no brass) to clean the media. Unless you have nasty old brass (which I did- sixty-odd year old in my case) it keeps them looking great and sliding in and out of battery well. Tend your brass- don't let it go flying and getting neck dents that when straightened, could lead to cracks.
There are many books on the subject (not counting the one I just wrote here) but you don't need to spend a fortune, just do everything to the highest standard of consistency and quality you can with the equipment you have.
I was shooting 10-round groups at ~1 MOA with this crap and it was certainly not state of the art. I just optimized everything I could to limit the number of things out of control.
I ran Varget powder on the advice of my instructor and it was very consistent for me. Federal primers ideally but at the time components were a bit difficult to get so that was one area where I would deviate from time to time. CCI was the other brand I would default to as well.
