Interesting.I basically just use a propane blowtorch and an electric drill with a spark plug adapter. Drop a case into the adaptor which exposes the neck then place perpendicular to the flame. Allow the case to rotate, then when you see the brass turn grey/blue drop it into a cold water bucket. I've done this with my sellior and bellot brass for 303 British and have got 5 reloads out of them. I also do it before full length sizing to ensure the brass is not work hardened.
Correct. My blowtorch flame is parallel with the bench surface so technically it's to the side. But yes, the case rotates within the flame to ensure a uniform anneal. Also the bottom two thirds are shielded by the adaptor, so although it gets warm you can be sure your primer pockets won't get nearly hot enough to deform.Interesting.
So the spark plug adaptor holds the casing in place and the drill allows it to spin above the blowtorch?
So after reading thru the case life thread, i was wondering what annealing techniques you folks are using?
