Greetings,
I just burnt up my last keg of H4227 powder. I went to order more then found out it is no longer in production. I see that IMR4227 uses different reloading data in the books, so I'm guessing it's not a 1:1 replacement. Is there a replacement out there for H4227? Thanks, Gos |

quick google search found this
I may have to call Hodgdon. I'm down to a couple pounds of H4227 myself. |

H and IMR are potentially very different depending on the powder. Sometimes they are next to each other on the burn rate, sometimes they are not.
In the case of 4227, they sit adjacent in the burn rate chart. To play is safe, why not ask the CS folks. http://www.imrpowder.com/burn-rate.html |

Thanks, Gos Gos, in general H and IMR powders with the same number should NOT, I repeat, NOT, be considered identical 1:1 components. They may have very similar burn characteristics, they may be side by side on the burn charts, they may have nearly identical pressure curves, etc. but they should not be considered the same thing. It is most likely that IMR 4227 will make a good replacement for your H 4227 loads but please revert back to basic reloading procedures when replacing any component. That is to say, start your load development all over with the new component. Do not take anything for granted simply because they are similar. MLG |
