Why do you get your brass wet after annealing ?
I heat the case neck/shoulder with a torch to achieve a light blue color (can bee seen in a dark room) in order to anneal the brass and then drop the case in cold water. When the brass is annealed it softens the brass that has been work hardened by reforming the brass case for wildcat ammo. A work hardened neck can split after the first firing. Case necks are annealed at the factory after forming for the same reason. Many factories polish the brass after annealing to make it pretty and remove the blueish tint on the brass below the shoulder to make it pretty. Many military ammo specs require that the brass not be polished after annealing as a QA check - it proves that the batch of brass went through the annealing process.
It is a myth that dumping the case in water "quenches" the brass - that works for steel, not brass. Annealed is annealed. Steel is quenched to retain a certain molecular structure for hardness, which except for files and drill bits, etc. is too hard and the steel needs to be heat treated (tempered), which removes some of the hardness and gives it toughness without removing all of the hardness. Annealing brass is similar, except heat can't harden brass it can only soften it. Brass is hardened by working it.
The water is to quickly cool the brass so that the heat does not travel to the case head. The case head is work hardened to withstand high pressure and give the brass some "spring" -- after the bullet leaves the barrel the pressure drops and the brass springs back and allows the case to be removed from the chamber. Allowing the head and body to be annealed will result in soft brass which will result in stuck cases or worse.
Also there are two levels of brass annealing... the light blue color indicates the temperature of the first level and it will still have some spring to it. If you get to red, the brass is dead soft -no spring - and is weak and very malleable... too soft to do its job of holding onto the bullet and springing back from the chamber.
