h-2227 powder ? imr2227?

dewcrew8 · January 6, 2010, 04:31 PM

I was giving a old paper 1lb can of hodgdon h-2227 powder and some of my cartidges use both h-2227 and imr 2227 powders are they the same ie(2227) the powder burn rate for them both is #53 for imr #54 for h . (lyman 49th ) or different powders altogether.the main thing i see when loading 44 mag is that the h-powder says to use magnum primers.

Historically no. They are not the same powder if you have that old of a can. Use the correct data.

I don't load for the 44 so I don't know about magnum primers.

Do you mean 4227? I don't pretend to know all, but I have never heard of 2227. I use a lot of IMR 4227. I don't believe Hodgdon makes their 4227 any more. Some would argue, but these are not interchangeable, according to some older data I have. Similar, but not the same, so be careful when working up loads.

All that said, I do not use magnum primers with IMR4227. I use it for .44 Mag, usually with CCI 300 primers. For the .460 Mag, I use non-magnum large rifle primers. I use many different powders for the .44, but the IMR4227 is the only powder I use for the .460 loads. Mainly because I shoot a lot fewer .460.

If you want to get into it, my understanding is that there has been some changes with the 4227s.

Prior to being bought, Hodgdon and IMR each made their own 4227 and they were different. When Hodgdon bought IMR, they found out the IMR out sold H by a lot, but wanted to keep their "extreme" powders research, so they dropped the IMR powder and the H4227 "brand" and put H4227 in IMR4227 bottles and called it IMR4227.

That was in one of the reloading magazines and online a few places. Do some searches if you want to verify it since I am doing this from memory.

I did notice a change in velocity when I went from true IMR cans to Hodgdon bottles for IMR4227.

I have been using the IMR4227 powder for the last year with no troubles in not needing a mag primer. However, I am using Winchester primers which are listed "for standard or magnum loads".
