I can answer a couple of these. The two sources for brass are Hornady and Starline. To the best of my knowledge, the brass that Cor-Bon uses is Starline. I use Starline per a recommendation from someone else and it's been great, no problems at all, not that Hornady is not just as good, but the Starline brass has proved to be top quality.

As for cast bullets, you can buy the same ones Cor-Bon uses and more, from www.castperformance.com

Anyway, those are the questions I can answer. Who's next?

On a side note, my 500 is going back to S&W tomorrow. Hopefully they can fix the barrel to cylinder gap and get my velocities up to where they should be.
