[caz223]

Your case life estimate is pretty good for .223 rem.
I could never get more than 5-10 uses out of a case.
However, most pistol brass lasts until you lose it, or it fails during case prep.
357SIG is the exception. It's life is limited like the rifles.
The problem is you didn't specify your needs regarding the amount of ammo you need is what calibers.
Most progressive presses don't do .50 bmg.
The ones that do aren't exactly free.....
