I have been thinking about doing this for some time, Ive done a lot of Copper annealing, but not Brass, but after reading "Dolomite_Supafly" post, I went ahead and got into it. Its real easy, and most of the $60. $45 to be exact, went for the Map gas torch, its a Bernz O Matic TS4000 (About $45) and its a good one, squeeze ON release OFF (auto light). Plus the cost of two cans of Map gas = $60.
I had the cordless drill, the 11MM deep socket with 1/4" drive, (for BR cases) and the little adapter to fit the drill.
I then snuck in to the kitchen and grabbed a 8" square 2" deep cake pan, for the cooling water, but any container will do, or you can let them just room cool, but I prefer water cooling.
On my first try, I did 50 rounds of 6BR Lapua brass in about 20min (one case every 24 sec), and they all turned out great, just like Dolomites. I was keeping them in the flame for 5 to 8 sec each, and for the 50 cases, I used about 1/3 of a can of Map gas.
Sorry no pictures.
