Loaded up 100x light .357 Magnum loads with Universal, trying out a new process for doing the charges. Previously I've tried to use either the powder drop or the Chargemaster with Universal, the former being generally a failure and the latter successful but intolerably slow. This time I wanted to try using both. I dropped all 100x in a row in rapid succession from the powder drop with the charge set to 0.1 grains under my target. Then for each round I dumped the charge out into the weighing pan and hit the trickle button once, twice, or three times, as needed to get the right charge. If it was over charged, I dumped a little back and started over. It was a fresh can, and I wasn't getting as much variability, generally -0.2 to +0.1 grains, which is probably livable as is, given that there weren't serious overcharges like there was with the older can. It would have gone a little faster if I'd dialed in the powder drop to the target load, as most charges were dead on to what I had originally set it to. I wonder whether the variability worsens the more the powder gets exposed to open air. It does change appearance noticeably, from a relatively uniform tan color when opened to a mixture of lighter and darker flakes as time goes on.
