BG, you can buy a Lee press at MidWay for $25, a set of Lee dies in 9mm for $33 (that's the 4 die premium set), Winchester JHP bullets at $13.50/100 and powder for $20 a pound. I own 2 9mm pistols that have yet to see factory ammo. If you've saved your brass then it's reloadable. Buy the above, a Lee Auto Prime (about $13) and some primers and you're in business for the price of 6 boxes of premium ammo.
You'll have enough supplies for your first 100 rounds and the next 100 will cost you about $17 for the primers and bullets. The savings really start to add up quickly and you get to practice with what you'll be loading for SD. A pound of TiteGroup contains 7,000 grains of powder and a 4.0 grain charge will do nicely for 9mm. That's 1,750 rounds you can load for $20. You'll never wear out the press or dies in your lifetime, if you don't like the powder dipper that comes with the die set then a digital scale will set you back $28.
Reload people! Reload! It's been a great tie in to shooting for me for the past 20+ years and it's saved me enough money to shoot much more than I should. The side benefit, as has been stated before, is that I know what's in every round because I put it there.
Good luck, stay safe and good shooting.
