Re: First atempt at anealing brass
Work hardening through resizing and shooting is the culprit of the split neck. If you "work" the metal enough then it gets harder and less ductile. Eventually, the metal splits since it cannot effectively flow during shooting or resizing. Annealing takes out and removes the work hardening. If you heat it too long past the "color shift", then you get "dead soft" conditions which lead to excessive ductility and "flow" of the brass. This will leave you with lots of trimming to perform as the brass will stretch way beyond what you want.
You do not need the water pan thing. Just roll them in the torch, watch for the color shift and set them to air cool. If your concerned about over heating the case body, your fingers will drop it before you can do any damage [img]/ubbthreads/images/graemlins/smirk.gif[/img]
Annealing should increase the neck life. Not much you can do about the head area failures from bad brass, poor chambers or excessive loads.
