Hodgdon discontinued IMR4227 made in Canada. They continue to buy H4227 from ADI but have renamed the old H4227 and now call it IMR4227. That was done because like said above, the IMR version was showing very good sales but H4227 wasn't. So, the real IMR4227 is gone and the old H4227 is now called IMR4227.
Please don't argue about this, just contact Hodgdon and ask them like I did.
This is similar to the reply I got from Hodgdon also.
If you go to Hodgdon's online reloading website and look under .357 mag and .44 mag rifle loads, you will see that they list the exact same powder charge for both H4227 and IMR4227 in recipes with similar bullets and those charges produce the exact same pressures and velocities.
What does that tell you?
