The load worked fine for me for years. Then, one night, the indoor range was venting in cold outdoor air (40 degrees) and the kaboom happened. I took the rest of my ammo home and dismantled and weighed their powder charges. The ones that I weighed were spot on. I figured, 1) hot Blue Dot load, 2) OLD BRASS, and 2) cold weather was just enough to push it over the edge.
