So, the other day I got distracted during reloading because my scale went out of calibration. While spending the next hour trying to clear the error message I moved on to something else and then a few days later realized I had left the lid off a container of powder. Anyone have any experience with this, any changes to the powder's performance? Already loaded up this years batch of deer/bear ammo, so I don't plan on using it for a similar load. It was H-1000 if that makes much/any difference.
