I'm going to break from the herd here.....

I anneal my brass by holding it in a flame of a plumbers torch and count to six or 7...and then into a small galvanized decorative bucket I bought at Walmart for a $1.00...

Then I let it air cool for 5 minutes or less...

The tumbler shines them up, if they need that.

I run my brass probably a lot more reloads than most do on the campfire...

a little prudence on the reload scale also helps stretch out brass life, quite a bit...

you guys are over thinking this stuff.....what makes ya think you need to dunk them in water? To Cool them?

air drying does that....not even using water eliminates the entire step...

I'm not experiencing brass failures, except maybe once in a blue moon... and that is after the piece of brass has seem 25 to 30 reloads or more...
so I must be doing something right....
