[QUOTE="Mikecr, post: 2431742, member: 1521"] It's not the same goal. Manufacturers [U]Full[/U] anneal at case forming stages. They have to do this and cheap flame annealing get's it done. We're reloading. Full annealing is not 'good' for us, and burning zinc out of our alloy is worse still. Zinc adds blue to flame which can mangle a color setting.. For reloading we need restoration to a good hardness, which partial work hardening of a strong alloy provides. There is no reason to full anneal, with a flame hot enough to degrade the alloy, and then try to restore a usable product with a bunch of extra sizing cycles. We don't have to do that. Dip your brass into an ~850degF liquid medium for ~10sec, and be done with it. It's never full annealed with this, doesn't change the alloy, just removing built up work hardening. No rocket science to do this the same every time. You can't get it wrong. Nothing is cheaper than a propane torch I guess, but dip annealing is still pretty cheap. [/QUOTE]
