Today I opened up a new can of H380 powder and while throwing charges, I am seeing a very small amount of pellet shaped powder mixed in with it. Even though it is a small percentage (30 or less individual pellets in a 40gr charge of H380), I don't recall seeing this before. Has anyone else seen this and is it anything to be worried about? This is a new unopened can so I couldn't have mixed it with something else by mistake.
