If you get the Laser Cast bullets, make sure you get them at a Cabela's price. I've never tried the other one, but I've heard good things about Rainer.
Here are some other suggestions for jacketed bulk bullets, courtesy of GBO Sponsor Midsouth Shooter's Supply:

As far as propellants, you can't go wrong with Bullseye. I haven't worked with WST, and AA #2 is okay. My latest find for .45 ACP is Scot's Solo 1000, now distributed by Accurate. It's hard to find, but the updated load guide is free. That's if you're feeling adventurous. Otherwise, if you've already got Bullseye, go for it.
