Yes Bob we can. That is why my number one rule is only one can on the bench at a time. Obviously I broke that rule and it cost me a pound of powder. It was a lot cheaper lesson than it could of been had I not caught it. My powder is stored next to the bench in a safe, so no reason to leave the extra can out ,just laziness on my part. So use my wake up call as a reminder to everyone, one can of powder at a time on the bench, DOESN'T MATTER HOW EXPERIENCED YOU ARE , mistakes can and do happen.
