I use basically the same setup.
I've tied everything from as hot as the torch will get it, to barely heating it.
Personally, I like to turn the lights down low and heat the brass till it just barely starts to glow, then quench it and drop it from the drill. This works good for me, tho some guys say to never, ever anneal without the tempature stuff on it. Thats horse pucky. I'm sure it would be ideal, but I'm mainly interested in case life, so this works great.
Dont ever get your brass red or white hot. EVER. It gets so soft you can pinch it closed with your fingers and ruin the brass.
