I like simple, hence all my bullets are cast from ww's, and either air cooled or dropped into a 5 gal bucket full of water right from the mold.

Personally I've found that a properly sized gas checked air cooled ww bullet with a good lube will rarely lead and hence water dropping them for hardness is seldom needed. This is for both magum revolvers @ 1200 fps and centerfire rifles @ 2000 fps. But if you are going for the highest velocities, then water quenching has it's place.
