Default H4895 vs. IMR 4895

Hey guys,

I'm brand new to reloading and just getting components together. I'll be loading for just my M1 to start out with. I have decided to go with IMR 4895 as my first powder to try. I recently found H4895 for sale for about $10 cheaper per pound. Is there a big difference between the IMR and the Hodgdon 4895's?

Getting excited to start reloading!

Thanks!

Not that big a difference in the two, but don't interchange load data. I like H4895 over IMR because it is less sensitive to temperature variations. They are both good for the Garand. I'm suprised you found H at $10 less per pound than IMR. Usually, the H goes for a bit more.

According to Hodgdon, H4895 and IMR-4895 are IDENTICAL, and Hodgdon makes them both.

Where do you see that?

Per Hodgdon's own chart, they have different burn rates.

It's my understanding that Hodgdon only distributes. Their powders are made by St. Marks Powder Co. in FL. Win231 and HP38 are the same powder, Win296 and H110 too. Many others.

I've used H4895, IMR4895, and pulldown RG4895. I have not found any differences in any of them as far as loads go. Always start 10% below starting load and work your way up with a new powder. ALWAYS.

I use a lot of IMR4895, You can tell by looking at the powder which is which. The IMR is dark grey and the H is like a grey-green and is also shorter. This may have changed as the powder companies seem to keep moving production. Last I knew the H came form Austrailia. I think the H meters better, but the IMR for me is easier to find. Be sure to use the right data, used to be about a grain difference in the two. Figure on about 145 rounds per pound, it is shocking how fast the hopper goes down. I started buying the 8 pounders...

Per Hodgdon's MSDS sheets, IMR4895 is made in Canada by General Dynamics. H4895 is made in Australia by Thales. Doesn't mean they are different, but compelling evidence they are not the same. MSDS sheets are posted on Hodgdon's web site.

H-110 and W296 are made in Florida and have the same alternate powder name indicated on the MSDS sheet. Ditto for H4227 and IMR4227 although they are made in Austrailia.

I find I use less IMR4895 in my Garands to get the same velocity as H4895.

I'd be interested in seeing the source of the info that Hodgdon says that H4895 and IMR4895 are the same.

They are not the same, as they are made by two different powder companies (as previously stated). Hodgdon has never made powder in their life. Bruce Hodgdon got his start selling surplus IMR4831 he bought from the U.S. government, and they have been selling other manufacturer's powders with the Hodgdon label on them ever since.
