propane torch and my fingers. i'll know when the case is hot enuff from my fingers.
Been doing it this way since reading the method in the old Shooters' Bible in 1958, as recommended by NRA. Heat on the twirling fingers is about as accurate as it can get. You drop the case into the bucket of water right under the torch and you're done. I found that the second firing after the anneal is the most accurate. Accuracy drops off after 4 firings so you just anneal again. Fast and accurate, and a helluva lot cheaper than the fancy machines. Faster than the candle method as well.
