Annealing

[Floridawally]

Kind of new to annealing and do not want to buy one of those fancy annealing machines yet so I am using the drill with a spark plug socket and a Coleman torch. 308 brass. 1 and a half inch flame from the torch. No water quench. I do it in room with dim lighting. I am using a metronome app on my phone to keep the brass in the flame for 6 seconds. I hold the brass about a quarter inch from the second blue flame or about in the middle of the 1 and a half inch flame.

Can anyone tell me if I am doing this correctly? I don’t want to over anneal and destroy the brass, my rifle or my face, but at the same time I have read that if I don’t get the brass hot enough it won’t anneal and I would be spinning my wheels. Any advice on how to determine if the brass is properly annealed would be greatly appreciated.
