IMR 4895 vs H4895 in 223

trobin · April 2, 2013, 07:28 PM

I was able to get a lb of IMR 4895. People I talk to use H4895. I wanna load it in mixed brass under 55gr Hornady FMJBT for a M4. Just looking for target rounds that will go bang. Any suggestions?

IMR 4895 works great in a .223 with that bullet weight. You should be able to find plenty of loads in most manuals or on Hodgdons website.

trobin · April 2, 2013, 07:47 PM

Since they have it I guess I better grab some more than

swcc22 · April 2, 2013, 07:48 PM

Hodgdon and imr are the same company so the two powders are prob the same.here is a pic from the latest hornady reloading manual

Probably not.
Hodgdon is the distributor, they do not own the IMR powder mill in Canada.
They don't own the ADI plant in Australia which is where H4895 is made, either.

There has been some blurring of the lines for things like 4198 and 4227 but I am pretty sure they still keep the brands of 4895 separate and distinct.

swcc22 · April 2, 2013, 07:55 PM

Well the addresses are close to each other and the phone numbers are the same

swcc22 · April 2, 2013, 07:59 PM

And besides there is no h4895 listed in the hornady reloading manual for that bullet you listes so best to go with the imr I use h335 myself and it works great

Thanks for the load data. I think Imma pick up another pound or two.

swcc22 · April 2, 2013, 08:16 PM

No problem oh the red blocks are the top end of the scale I load mine at the 3000 mark well between the 2900 and 3000 its going about 2950

trobin · April 2, 2013, 08:25 PM

Would you mind texting me the data for 25-06 117 sst and 270 150 sst??? 337-344-2899.

oldpapps · April 2, 2013, 09:27 PM

OK, I'll try to respond to each of the questions, as they progressed.

I have and use both IMR and H 4895 powders. I like them both and don't see any difference in the end results. NO, THEY ARE NOT THE SAME.

H 4895 is my 'goto' for 75 grain AMAX. IMR 4895 is one of my favored powders for 50 grain JHPs.

Their are many suitable powders for use in the .223/5.56. I suspect that if one were to ask, one would get dozens of responses. I will give mine now. I prefer 748 for 50 to 68 grain bullets. Over 68 grains and I go with H 4895. I have used BLC2, 3031, H335 and Varget. Note, I don't like Varget.

Now to your original thought. So, you got IMR 4895, go with it, it's good stuff. I actually get higher velocities with accuracy out of my bolt action .223 Rem with tight chamber, when using IMR 4895 (Averaging 3017fps with 50g JHP).

P.S. I don't know what 25-06 has to do with this.

Load with care and enjoy,

OSOK

Oldpapps.

Thanks for the response. Since swcc22 had his hornady manual out I asked for the load data for two particular hornady bullets. Lol

j357 · April 3, 2013, 06:37 AM

One of the most recent issues (Feb-Mar 2013 IIRC) of Handloader has a good article on differences between the H and IMR 4895 powders. They are not interchangable.

I have been very pleased with the following load in swcc22's pic. 23.5 IMR4895 using the 2267 bullet shown in bottom right.

If you plan on loading more than 250 to 290 rounds of .223, you better hurry back to your source as thats all you will get from a pound.

higgite · April 3, 2013, 01:31 PM

I'm guessing they are not the same since Hodgdon lists different loads for the 2 powders with the same bullets.

trobin · April 3, 2013, 06:30 PM

I picked up another lb and a lb of hybrid 100

**Unclenick** · April 4, 2013, 03:37 PM

Hodgdon bought IMR and now distributes both Hodgdon and IMR as well as Winchester powders (under license), but the Hodgdon stick powders are made by ADI (owned by Thales) in Australia as part of their Extreme line of stick rifle powders, which are modern formulations for lower temperature sensitivity. IMR is made made at the Valley Field plant in Canada and is still the same basic formulation it has been for decades.

H4895 has a burn rate similar to IMR 4895 for historical reasons. However, H4895 has several characteristic differences. It tends to burn a little faster and take a little less charge weight in most load combinations. It has that greater temperature immunity, so you can expect the two will show more performance difference at temperature extremes, particularly in a cold barrel. It has the property of working better in reduced loads, and Hodgdon says you can reduce their listed loads by up to 40% and still have it function (albeit inefficiently).

trobin · April 5, 2013, 07:15 PM

Well I loaded 60 rounds today. 20 w/ 23.5 grains, 20 w/ 24 grains, and 20 w/ 24.5 grains. Plan to shoot em Sunday.
