Pretty good list, you aren't scared to buy some good stuff; some options you may want to look at also;
Matchmaster die----Hornady or Lee quik change bushings, unless you buy a Co-Ax press
RCBS Rock Chucker press-------------could also look at MEC or Forster Co-Ax, better primer handling on either one than on RC. Just as tough.
M
itutoyo 6” calipers
Autotrickler V4 with A&D fx scale
Area 419 funnels---- may want to look at RCBS kit---See F-Class John vids
Henderson neck trimmer
Powder
Casings
Bullets
Primers
Spray lube------ --------------add a Forster or Lyman dry lube neck brush kit
Frankford Tumbler and media
Frankford media separator
Garmin Xero
Kestrel 5700X Elite
I'd add;
Derraco/Ugly Reloading PCPS (takes Lee shellholders), or Lyman Accuprime Auto priming tool ( takes regular shellholders like RCBS)---see Ultimate Reloader vids on either, or F Class John on the PCPS
Derraco comparator sets---Amazon or Ugly Reloading
Primer pocket uniformer---Sinclair or K&M
Frankford Arsenal reloading trays for magnum ctges (ie 300Win Mag)
MTM ammo boxes ( suitable for 300Win Mag size)
A beam scale for backup and verifying any electronic scale Burstfire annealer, has a prep ctr built in as a bonus. Also has an induction annealer, it's too new to have a proven track record yet though.
RCBS bullet puller and collets, are better collets than the Hornady one.
Shellholder, unless you buy a Forster press
Maybe Stuff;
---if you are an accuracy nut, K&M arbor press and Wilson seater die.
May also want a decap die---Lee works fine in any press, get some extra pins. Mighty Armory and FW Arms are the top of the line ---one of them is too short for Co-Ax press though
Expander mandrels, wait til you get brass to determine which ones you need.
Inline Fabrication press mount system, is worth the money
