It makes sense to hand load 9mm if you spend a lot of time at the range. You still want to buy ammunition for self defense, since that is hotter than you would be inclined to load yourself, and legally more defensible. If you reload, you may not save much money, because you tend to shoot a lot more. Group sizes shrink about half with reloading compared to WWB, because you are more consistent and select components more carefully.

In any case, small stuff like 9mm is best done on a progressive press. This will cost about $300 to set up with dies and accessories, but you can turn out 400-500 rph without breaking a sweat. That leaves you with more time for shooting (and the need to reload more). I have a Dillon 550B* press, which I highly recommend. Any will work just as well in most respects, but Dillon has it for priming, metering and customer service.
