Yes, basically. I use a bin instead of a bucket so I can dunk in the tray flat and not bang the bullets together too much while they’re still “wet” from powder coating. I based my method from some charts and videos I’ve seen with quenching before or after. See this video, that’s how I decided on what method to use.

Water quenching hardens a thin surface layer on the bullet surface, it doesn't have any effect on overall bullet performance on game. A harder surface layer on a lead bullet could prevent lead fouling in some circumstances - but if the bullet powder coated I don't see any useful reason to water quench it too.
Water quenching does harden the surface of cast bullets but the increased hardness doesn't go very deep.You obviously know more about cast bullets than I do. Like I said, this is solely based on internet and YouTube research. Water quenching seems to be an accepted method to harden cast bullets.
