Just found this on Hodgdon's site,,,

In response to a growing number of inquiries from the reloading public, Hodgdon Powder Company, Inc. has undertaken the evaluation of Triple Seven® and Pyrodex® for use in volumetric powder measures designed for use with smokeless powder.

Testing was performed by:

Canadian Explosives Research Laboratory
Global Environmental Solutions
Australia Department of Defense, Defense Science and Technology Organization
ADI (Australia Defense Industries)

Characteristics of ignition tested:

Friction
Electrostatic Discharge
Impact
Ignition Temperature

Test results for Triple Seven and Pyrodex were then compared to Clays® smokeless powder.

Evaluation of the test results reveals that there is no increase in risk of ignition from the use of Pyrodex and Triple Seven when compared to smokeless powders. Further, burn tests indicate that there is no issue with critical column height in the factory supplied powder hoppers with Pyrodex, Triple Seven or our smokeless products. These findings would be consistent with the United States Department of Transportation classification of Pyrodex and Triple Seven as flammable solids rather than as explosives, allowing them to be transported in the same manner as smokeless powder.

Hodgdon Powder Company will begin changing our warnings as soon as possible to reflect the results of our testing. We will now state that Pyrodex and Triple Seven may be used in any volumetric powder measure approved by the manufacturer for this purpose.

We have provided this information to the powder measure makers and have asked that they consider changing their warnings in a similar manner. If there is any doubt about the suitability of a specific measure, the user should contact the powder measure manufacturer.

If you should have any questions about the use of Triple Seven or Pyrodex in powder measures, please contact our Customer Service staff. 913-362-9455 or [email protected].

* Warning - Always use care when handling any gunpowder. Follow manufacturers instructions for proper operation of your powder measure. Read and understand warnings on powder label.
