Quick, Cheap, Easy, Uniform Annealing
Proper annealing greatly extends the service life of cartridge brass. After years of fiddling with gas torches, my wife's gas range, and inductive heaters, this is the slickest method I've found. It produces very uniform annealing. It works much better if the brass is deprimed. Rinse well, and, if desired, blow dry with an air compressor.
