Cast is cheaper and they cause less wear on your barrel. Other than that, jacketed bullets tend to be superior for accuracy and speed.
Cast bullets generally can't be driven as fast as jacketed. In your 9.3 I bet you'd get speeds of 1800 fps with cast w/gas check bullets with no problems, but faster than that may or may not be possible. Plain base bullets can't be driven as fast. Alloy hardness and bullet speed are the only way to control expansion in cast bullets, very hard cast bullets shatter instead of expanding in game, very soft ones may deposit lead in your barrel and accuracy can suffer.
The 9.3 is a bore size that should work well with cast bullets, it is easier to cast accurate lead bullets of large diameter compared to smaller calibers. Cast rifle bullets under 7mm diameter require extreme attention to detail for consistent results.
I get quite a bit of satisfaction casting, loading and shooting my own bullets. Finding an accurate bullet style, alloy mix, powder load, and size/ seating depth is another hobby that has pulled many shooters into its vortex. Lots of fun if you like that sort of thing. The very best cast bullets can be as accurate as jacketed and can be used successfully to hunt medium - small big game like deer, even larger game once you have some experience.
