I swage my own bullets, and currently make .358 rifle bullets. I'm also set up for .312's and .323's, but I'm still in the early developments stages with these diameters.
I'm unfamiliar with the 7.92 Kurz cartridge. If its a handgun cartridge, you may be able to use a strong reloading press to swage bullets for it with appropriate dies. Normally jacketed rifle bullets above .243 diameter require a specifically designed swaging press to properly make bullets. Pure lead bullets can be swaged on a reloading press, but harder lead alloys can present a problem, and depending on hardness, can break both dies and presses.
Corbin makes excellent dies and presses as does RCE (at a lower price) (
www.rceco.com). If you are making handgun bullets, C-H (
www.ch4d.com) makes dies for reloading presses that can be had within a shorter time frame and at a lower cost than either of the others.
A standard reloading press can generate around 25,000 to 30,000 psi of pressure, while the Corbin "S" press can generate about 130,000 psi and the RCE Walnut hill press can do something in the order of 180,000 psi. Heavier hand presses and hydraulic presses go up from there. The greater the pressure, the better the metals are able to flow and form higher quality bullets.
