In the process described above,
Where are you going to find suitable 'Cartridge Brass' alloy bar stock to start with?
When I hand machined oddball Sharps cases I ran into the issue of alloy mixing, with common 'Brass' rod being way too hard to start with, and without the zinc alloy being correct the cases split.
If you want to harden the head, you will have to machine the case blank, bore the bar stock, build a socket die to insert head into, and build an impact ram to fit I to the case.
Using something like an air hammer you would be able to work harden the head area without hardening case walls.
Then you would have to cut rim & primer pocket, this will require a mandrel inside the case to keep it from deforming as you clamp the case by the walls to cut the rim/primer pocket.
Then you could get around to annealing the top of the case for neck/shoulder forming...
Back before long stroke hydraulic presses were invented, manufacturers tried both casting case blanks and machining, and cutting billet into blanks (what you are talking about).
Copper can be spun (rimfire) but brass has to be extruded/drawn and/or machined.
Good luck.
