Go to the
Hodgdon website, and they say that H4227 and HS7 are being discontinued. I have read from other websites what Hodgdon intends to do is sell their H4227 as IMR4227, and the IMR4227 won't be made anymore; you will be buying H4227 in a can labeled IMR4227. Since H4227 is one of the powders that was re-formulated as an "Extreme" powder with reduced temperature sensitivity; but the IMR line is the original and better known line of powders, this almost makes sense. I wouldn't be surprised to see the same thing happen with other powders that are duplicates between IMR and Hodgdon.
