Depending on your budget, here are some good things to get. There are cheaper options and like has been mentioned, you can get kits that have the vitals, but if you want to get more into precision you will replace some stuff and add to the set with additional things.
These are just my thoughts...doesn't mean you need all of this now. Some have less, some have more. Midway, Sinclair, Brownells, Graf and sons, and plenty of other places carry this. Some have items in stock when others don't and some have better prices and shipping costs, and some ship quickly (Midway is good about fast turnaround).
Forster coax press
Redding Type S FL and Seater dies. May need VLD stems for seater and may need neck bushings for FL or neck sizing dies.
Deprimer, Lee is easy
Hornady Lock-nLoad tool to measure to lands and modified cases for each you are reloading for
AMP Annealing (since you have expensive brass with the Nosler rounds)
Good calipers (I have Starrett mechanical)
Scale (some like a beam, I got digital and went with a GemPro, then RCBS 2000 to an Fx120i with auto trickler)
Powder thrower (I like the Lee scoop set to use with the auto trickler) but can get RCBS or some other - since you load for multiple cartridges, get one with a micrometer so you can get back to each throw pretty easily)
Bullet comparator (I have Darrell Holland's) and bullet length / COAL gauge (Hornady)
Headspace gauge (Hornady, or I got Larry Willis' gauge and think it is money well spent)
Runout gauge (I have Darrell Holland's)
Neck thickness micrometer (I have Darrell Holland's)
Some type of brass cleaner - I started with cob media tumbler, then got Stainless and am very happy)
Bullet puller (Forster if you get the coax, grip-n-pull if not)
Case trays
Ammo boxes
Priming tool (I have Sinclair)
Case lube (many use imperial)
Case trimmer
Shell holders
Neck turning kit if you want to do that
Stuck case remover - I have one but haven't had to use it yet. But want to be able to get it out when it happens and not have to order it.
I am sure I forgot some things I have but that covers most of what I have. You can get by with less, and you can get by with cheaper options on many things. I have found that if I buy the cheaper option I often replace it for more precision or efficiency later, so take that into account. I would have spent less if I bought this stuff first, but it is also important to find what you want to sink your time, what you want to measure, how precise, how efficient, etc.
Keep all the little bits that come with this stuff even if you don't know what it is. Eventually you will probably need it. Keep all the instructions - I throw them all in a ziploc bag for in the future. You can probably find them online but some stuff is obscure.
