To the OP, I was asking the exact same questions with a similar thread recently and got some great advice. I'm still waiting until I have a bit more money before investing. As someone has suggested, I prefer the buy-once-cry-once approach (I don't buy cheap tools). However, trying to adopt too many new skills at once could be an exercise in frustration. It is for that reason that I will be trying to keep things simple and only spending top dollar on components that are extremely well-built, but not complicated. For what it's worth, here is my short list.
Forster CoAx Press - Simple and well-built
Unknown Die Set - Originally, I was sold on the Redding competition dies, but as stated before, there is a much higher level of complexity, and I would rather develop the basic skills first. Still researching this one, but I am considering Redding Premium series. Lots of other good dies in that price range
Hornady Die Lock Rings - No brainer. Great locks without any risk of damaging threads
Lapua Brass - Best brass available with the most reloads. Ask anyone on this forum
CCI BR4 Primers - Mostly because the factory is very close to my house and I like to buy local, but great primers nonetheless
Powder and Bullets - Whatever works. Berger, Lapua, and Nosler are on my short list
Balance - I'm picking this up for free from my research lab because it's broken, and I know I can repair it. Accuracy is .0001g (not very helpful for you)
Almost everything else - Going cheap, and I will invest in better equipment as my skill level exceeds my handloads (if that ever happens)
Best of luck,
1) Forster Co-ax press is a good choice. Quick die changes and the S-jaws are very nice. Tho I prefer FL sizing on a press with a sturdier shell holder system. So I only use my Co-ax for seating. You can buy a standard shell holder adapter for the Co-ax, but then you take away the convenience of the S-jaws.
2) For the price of Redding Competition dies, you might as well go with a Whidden die set. Much better quality and custom fit to your chamber for nearly the same price.
2) For lock rings, I prefer Forster. They are designed to work perfectly in the Co-ax press so it just makes sense to use them if you have that press. Also have cross bolt locking mechanism that won't damage die threads.
3) Primers can be like bullets. Quality may change lot to lot. So for me they fall in the same line as bullets and powder with "whatever works". I always have many different brands of primers on hand for testing (CCI, Federal, Remington, etc).
4) Good list to start, but certain bullet manufacturers like Berger and other custom bullet makers (Vapor Trail, Barts, JLK) will yield much tighter tolerances and consistency with bullet dimensions and weights than brands like Nosler and Hornady. Lapua bullets can be good, but I've never got them to shoot quite as good as Berger in any rifle. Nosler bullets are not very consistent. You can sort them out, but you will have a lot more cull pieces than you would with Berger and Lapua.
5) Don't know if I would risk a "broken" scale. It needs to be extremely accurate and always repeatable. Even if you get it running, there's no guarantee it will work right. But since it's free, I suppose it's worth a shot. If it doesn't work out, look into buying a AND FX-120i scale.
6) You can go cheap on some things, but dont go cheap on a neck turning tool. That is a very important piece of equipment for case prep and it needs to be very precise. I like the 21st Century neck turning tool, but there are other very nice neck turners out there that will keep tight dimensions.
