Anyone ever received a cannister of powder that has been tampered with? I just received an 8 lb cannister of Alliant MP 300 from Natchez that had the plastic seal broken on the lid and the internal foam/paper seal was not attached to the mouth of the jug inside. I called Natchez and they said they would submit something to UPS who would get back to me within 5 days. I don't know whether someone decided to inspect the contents, whether some was removed or what? But I can't use it until I know more. It was expensive and shipping was expensive!
