I have some old IMR-4227 (8# metal can) and also some newer H-4227 and wonder about switching over to H-4227 when I'm out of the IMR. So the question would be ... what, if any, interchangeability would there be between the two powders? I realize they do not have the same burn rates and aren't exactly alike, but I had to ask.
I started with IMR years ago the then drifted into H-4227 for some loads but wonder what to do about my IMR loads when I can't find it anymore.
Nice, easy solutions are always so convenient ... but rarely exist ... or do they?
