    When starting a new lot of powder, of the same powder, do you do a small run of test loads to make sure the powder is the same? Lets say the powder was purchased a couple year from each other. I know it should be the same, but I was wondering if any of you do this for safety measures?

    I like to run some of the new lot over the chrony to see how it compares to my previous data. If the charge is near max I will back it off and work up. Usually I find the new lot to perform just as the old. It never hurts to take extra safety measures.

    I don't spend a lot of time obsessing over lot numbers. In today's world, manufacturing of just about everything is so highly repeatable from "batch to batch" I don't see the issues like "back in the day" when it was more like a bunch of "mad chemists" running the plants.

    If I were to be totally anal about my loads like some who are competing, and winning or loosing hangs on how many fibers in the target are torn at the edge of a group, maybe so.

    For those who worry a lot about lot to lot variations, just buy a couple of cases containing 8# jugs. Wait, maybe that's why I don't notice much "lot variances":laugh: My annual powder orders range in the 40-48 lb range.
