I sometimes (well, often) leave my press set up (with powder in the hopper) for weeks if I'm doing a big run of a particular cartridge. Never had any ill effect that I could detect. I've never detected any discoloration of the plastic in the Lee powder measure, and if I have it set to throw a certain grain weight on Monday, it seems to throw that same weight when I get back to it on Thursday. (I do have an old RCBS uniflow that I bought used 30 years ago that had badly discolored plastic when I bought it.) As for the safety issues, I still only have one powder in use at a time, and I keep the container on the table until I'm finished with it, the scale is set for the weight I'm set up to throw, and when I've been away for a day or a week, I'll weigh the first one or two I throw. Continues to work for me!
