From what I have read... The IMR formulation of 4227 has been discontinued. The Hodgdon formulation of 4227 has replaced the IMR formulation and is being sold under the IMR label and the H4227 label is now gone.

In any event, both were so close the data was pretty much interchangeable even though the powders were not identical.
