you guys are over thinking this stuff.....what makes ya think you need to dunk them in water? To Cool them?
air drying does that....not even using water eliminates the entire step...
Here is the reason to immediately quench annealed cases…
“ Cartridge brass is only hardened by cold working. The crystal dislocations caused by the cold working lock the crystal lattice and make it harder and more difficult to form more dislocations thus increasing it strength. When brass is heated, new crystals nucleate at the dislocations and the new crystals are small. If the brass is quenched at this point, the brass retains the small crystals and is annealed with very few dislocations and is stress free. This is the condition you want for your case necks. If the brass is slowly cooled, the small crystals begin to coalesce and grow into larger crystals and the properties suffer because the large crystal boundaries are not strong. Also stress corrosion cracking can more easily occur at the larger crystal boundaries.“
