RCBS press....used or new.
I like Forster dies (if you can't afford them I would go with RCBS or Hornady)....used or new.
You'll need a good scale an RCBS is hard to beat....used or new.
Powder trickler....used or new.
Pick up a used Wilson case trimmer on here or ebay....best there is and they last forever.
Don't go cheap on a dial caliper (you could make do with a cheap one) but I'd suggest buying a used Starrett....look on ebay.\ used.
Later comes the Stoney point tool and bullet comparators to measure with.
Remember cheap tools tend to follow you around for a long time.
The above ^^^ and look at the Lee 280 Rem 3 piece die set (seater, full length sizer, and factory crimp die) add to this a Lee collet neck die and a Redding body die. Then later on look at a Forester bullet seating die as the Lee seater die will produce < 0.001" runout pretty much most of the time.
The 280 Rem set is used to form brass from other cases such as 30-06, 270, and 280.
For the 280 ai I use 30-06 cases , they come out a bit short but that has not been detrimental to function or accuracy, just ensure carbon is removed when cleaning the barrel.
