Notwithstanding the fact that every powder is not created equal, I was examining 3 different powders (2 of which I just picked up) and they all look very similar. I know there's variables not seen by the naked eye and burn rate is obviously different. I guess if nothing else-just a reminder to keep your container off the shelf so you don't forget what you're using! The closeups represent the order of the powders in first pic.
