Unique Powder Consistency

Unique Powder Consistency

Unique is a popular powder and we receive many inquiries about powder consistency. The powder is popular, but it’s density varies more from lot to lot than any other powder. The auto disk system uses a value supplied by the powder manufacturers for each of their powders called the Volume Metered Density (VMD). We use this VMD number in a formula to determine the size cavity that should be used to dispense a given amount of powder. The system works well as long as the actual density of the powder remains the same from lot to lot. We factor in the variation and that is why some loads came up weighing less than the data called for. We want the error to be on the safe (low) side and not the high side.
