Every time I finish loading a batch of ammunition with a powder measure or trickler, I'm always careful to get every last particle of powder out of the device so that I'm not inadvertently mixing powders the next time I use that piece of equipment. And every time I'm doing that, I always wonder how much powder mixed with another powder would produce noticeable changes in performance. If three granules of AA#9 got mixed into a 5.0-grain charge of Unique, would I be able to tell when I fired that round? I'm guessing not, but what about a tenth of a grain, which would be about 2% of the charge? At what point does mixing powders, intentional or not, become dangerous?
I'm not going to change my practice of removing every last bit of powder when I'm done with a piece of equipment, because I don't want to learn the answer to my question by mistake. I'm just curious. I suspect the answer varies based on which powders are involved.
