MUST HAVE TO START--NO WAY TO GET AROUND IT:
Manual--I like Sierra and Hornady bullets so I have each company's manual
press
Calipers (don't need Starretts since Chinese communist ones will do but measuring overall length is absolutely critical), ~$30+ or so for Chicom, $150-ish for Starrett/Brown & Sharpe/Mitutoyo)
Dies--one set for each cartridge you want to load, $45+ per set
shellholders (usually can use one for a number of different cartridge), ~$8
scale (balance-beam units will work but they're no cheaper than a battery-operated electronic one since those can be had for $40-$50)
consumable supplies (powder, primers, bullets--should be self-explanatory)
loading block--they're cheap and it beats having a bunch of cases rolling all over your workbench and spilling powder when you bump it, $10
funnel for pouring powder into cases--I use a RCBS version that works as a scale pan/funnel combo, $8 for the combo one I use
case lube--I use Hornady One-Shot aerosol since getting a case stuck in the die is a cast-iron BITCH to deal with, $10
tumbler+media, $60+
NICE TO HAVE, BUT NOT CRITICAL RIGHT AWAY:
bullet puller--you're going to screw up a couple cartridges and this'll let you save the components, $20
primer pocket uniforming tool, $25 or so
decapping die for punching out primers--I use mine prior to tumbling/resizing since the tumbler can clean out the primer pockets some, $25
flash hole deburring tool, $20 or so
combo case mouth chamfer/deburring tool, $20 or so
case trimmer--you can get buy for a loading or three without one, but eventually the brass will stretch and you'll have to cut it back to factory length, $75-$200
powder measure--I use mine to throw charges a grain or two short, then use a powder trickler to bring it up to the exact weight I want. You can actually get close with a set of measuring spoons (i.e. 1 tsp of powder will be close but short for my 300 gr. 45LC hunting load) if you experiment with it some, $80 and up or $25-ish for the LEE powder dippers
powder trickler--used in conjunction with a powder measure. You can gradually trickle powder in if you have a small amount on a bit of paper but a $20 trickler (I use a Redding version) is a ton more convenient, $12-$25
WHEN YOU HAVE MAD MONEY/LOTTO WINNINGS:
neck turning tool to uniform neck thickness $60-$200
hand priming tool--some folks prefer them for priming since you can have slightly better "feel" for when the primer is completely seated, $40-$125
primer pocket swaging tool--needed for removing the "crimp" in .mil surplus primer pockets, $80-$120
cartridge measuring tools for setting bullet seating depth off the ogive vs overall length, $100 or so for all the widgets you need to get it to work
concentricity tool for measuring how straight the bullet is seated, $90
