That's pretty Kool and all,I use an Annealing Made Easy machine. I bought it when I was shooting prairie dogs and had to load a lot of cases. It costs about $1,500. That is expensive as hell but it works great and takes about 5 seconds/case. A word of warning: do not touch the annealed case until it cools off. Every one I know who has one of these machines, including myself, has done so and burned their fingers. Also do not put a loaded round or one with just an unfired primer in it into the machine. If you are annealing a lot of cases one with a live primer in it might be missed especially if you do not size the cases prior to annealing.
I got to lookin, though and this thread is older than when this anealling machine was invented.
I might start trying to do some more anealing again soon.
