In the Hodgdon 2015 Annual. There were three write ups, by 3 authors, about the three new powders. Two of of the three claimed after to speaking to senior Hodgdon officials that these new Enduron powders were the first double based powders in IMR history. I wrote Hodgdon last week explaining this, and asking why the MSDS showed that they were single based powders. They are classified as double based powders. This is not a slight to the writers who authored the write ups in the 2015 Annual. I think each of the writers is an excellent writer and hold only the highest regard for all of them. I just hate nonsense when new powders are brought out. At least Hodgdon did have good data when these powders came out, unlike other numbers of recent history.
