It's not that critical. 400-410 is probably better though.

Does the 10 minute timing start from when the powder gets a wet look (around 325*) or from when the temperature gets up to 400?
Just go for 20 minutes from the time you put the bullets in the oven. Too long is OK, within reason.

Can I drop straight into water to harden, or do I have to let them finish curing, then reheat and quench? Will it flake off if I drop them immediately?
Do not drop hot powder coated bullets into water; pour the water on them instead. Moving them when they are still hot out of the oven will pull the coating off, it has to cool down to fully cure. You don't have to do a separate heat treat cycle though. I take the tray out of the oven, set it on the garage floor, and pour a pitcher of cold water on it, making sure all bullets are quenched as fast as possible.

Thanks
