I' m not a fan of letting my rifle hand loads set for weeks at a time. Pistol who cares. I just cleanded up 300 pieces of brass and had the day off, so thougth about priming the brass then putting them back in my storage boxes. Anyone else do this? Couldnt imagine any ill effect....But as an OCD reloader just wanting feedback. It's not like the cardboard boxes keep out humidity etc. unlike a sealed jar of powder
