Has H4227 been Discontinued or Not?

[Contenderizer]

For months I have been told that H4227 has been discontinued, yet it keeps showing-up in current loading data. The latest issue of American Rifleman has a article about the .500 Wyoming Express and a couple of the recommended loads use H4227. I realize that it takes a while to get the stuff out of the supply chain, but what's the whole story?

1. Has H4227 been dropped?

2. Can IMR4227 be substituted at the same level of charge?

I have been avoiding purchasing H4227 (and substituting IMR4227) thinking that the supply will soon be exhausted. No sense in working-up a good load only to find the powder is no longer available.

Hodgdon isn't listing H4227 among their powders on their website. That says to me that it's discontinued.
Loading data in print can have a very long life. With some less popular cartridges, you'll see the publishers of manuals reprint the same data for 2 or 3 editions of their manual, so the new manual you bought last week could actually have data in it worked up 20 years ago.
I would NOT assume that IMR-4227 is a direct substitute. IMR's version is similar, so it would be a good choice for any application Hodgdon's 4227 is, but I'd work up loads from the beginning for the IMR powder.
Just a guess, but I suspect that when Hodgdon bought IMR, they decided it wasn't cost effective to make both powders.

Hodgdon and IMR are the same company now. Most of the powders are different. However, I understand that a decision was made to only make one 4227 because they are so similar to almost be identical. I understood it was the IMR that was to be dropped, but if it was the H that got dropped and the IMR is still being made, well that is OK too. It is just a great small capacity cartridge powder and my favorite in 218 Bee standard and 32-20 heavy bullet loads.
Best,

H110 is a better powder for the fastest loads in the .500 anyway. I use H110 in all the magnums - it is simply the best powder for a wide range of magnum cartridges.
I switched a long time ago from the Winchester powders because they kept deleting powders without any replacement. Hodgdon has them all - if there is a cartridge made you can find the best powder for it at Hodgdon!

H110 is W296....

I`m pretty sure H4227 has been discontinued. Hodgdon likely will offer data for some time to cover the powder that is still out on the shelves or in customers hands.
Hodgdon now owns IMR powder and they would be the best source for your question. They should be able to tell you if data is interchangable between the two, or if not, offer data for the IMR line.

Hodgdon now is the distrubutor for Winchester and I heard VV powders. They should offer help/data with all powder 4 brands now. Hodgdon, Winchester, IMR, and VV.

"They should be able to tell you if data is interchangable between the two, or if not, offer data for the IMR line."

I don't think they are EXACTLY the same, however, regardless of which one you have, you can use the starting from either one to do your load work up.
