[QUOTE="Laguna Freak, post: 1952719, member: 87188"] Annealing has a minimum temperature required to re-sort the brass molecules to reinstate the desired flexible strength. Consistency is indeed important to consistent accuracy results. Under-annealing (not annealed) is as useless as over-annealing is destructive. Annealing with a torch by hand is a bit of an art that requires focus. Especially when annealing 100+ cases at a time. Its not surprising that many people prefer to use a machine. My ability to get the case neck and shoulder annealed adequately by hand is somewhat dependent on the case. E.g.: I can turn off the lights and roll a 30-06 or 300 WSM case in the blue tip of the flame for 6 seconds +\- and watch the brass just start to glow red Inside the neck without burning my fingers. At 7 seconds I gotta put it down NOW. Shorter cases like 308 are plenty hot on the finger tips by the time the case neck is starting to glow red on the inside. It aint for the faint of heart nor those with highly sensitive fingertip pads. [/QUOTE]
