Stupid question about powder

butta9999 · May 21, 2009, 03:35 AM

For example is IMR 4831 the same as H4831. Does Dupont powders still exist or have they been taken over by Hodgdon powders.

It's hard to get info from local dealers as not much of the powder is used in Australia

steveno · May 21, 2009, 03:46 AM

IMR-4831 and H-4831 are not the same powders. IMR-4831 is slightly faster burning

kiwi56 · May 21, 2009, 05:00 AM

Most of the Hodgdon powders are manufactured in Australia by ADI
AR2005 = H110
AR2206 = BLC2
AR2207 = H4198
AR2208 = Varget
AR2209 = H4350
AR2213SC = H4831
AR2217 = H1000
AR2225 = Retumbo
AR2218 = H50BMG
Most of Hodgdons shotgun/pistol powders are also made by ADI

G'day. Here are a couple of notes from the Sierra 5th Edition Reloading Manual, powder burn rate chart.

Quote:

Universal Clays should not be confused with Hodgdon’s Clays, or International Clays. These three powders are different and should not be interchanged.

In manuals or writings published before 1973, any mention of 4831 will refer to Hodgdon’s H4831. In older manuals, it was customary to list the powder simply as A4831” with no designation connecting it to the Hodgdon line. The reason for this is simple; prior to DuPont’s introduction of IMR 4831 in 1972, the surplus 4831 sold by Hodgdon was the only powder to carry this designation. Despite their similar nomenclature, these two powders (IMR 4831 and Hodgdon 4831) are not inter- changeable and must not be confused. IMR 4831 is significantly faster burning than H4831, and may produce dangerous pressures if used with data developed for the latter.

Here is the list of ADI / Hodgdon powders.

ADI / Hodgdon Propellants

ADI Powder/Hodgdon naming
AS30N.................Clays
Trail Boss.............Trial Boss
AS50N.................International
AP70N.................Universal
AR2205...............H4227
AR2207...............H4198
AR2219...............H322
BM2....................Benchmark
AR2206H.............H4895
AR2208...............Varget
AR2209...............H4350
AR2213SC...........H4831 / H4831SC
AR2217...............H1000
AR2225...............Retumbo
AR2218...............H50BMG

For more details on the ADI / Hodgdon powder look at this thread.

Used to be, not any more.

kiwi56 · May 22, 2009, 04:11 PM

Hodgdon have not only taken over IMR (Dupont) but also Winchester (Olin) powder as well.

butta9999 · May 23, 2009, 02:27 AM

OK so in saying that, are the IMR powders still avaliable or have they been discontinued by hodgdon powders.....

Thanks shoney confusing but understandable.

shooter007 · May 23, 2009, 02:31 AM

Dood Hodgdon and IMR are seperate. I have a 270 Winny. It loves the Hodgdon H4831, it gives a smooth slow burn that gives me over 3000ft a sec with sub moa results. If you were the PICASSO of reloading this would be common knowledge to you.

butta9999 · May 23, 2009, 02:35 AM

Ha just not too familiar with all the powders, its hard to get anything but ADI here. I have some IMR 4320 and 4198 which i got years ago and is running out. Works real well for my .243 and .222.

Knowledge is power shooter, the more i know the more of an artist i become.... well i hope anyway, these forums are a big help.

Even PICASO had to start somewhere.

kiwi56 · May 23, 2009, 03:12 AM

IMR & Winchester powder are still available but it comes from Hodgdons have a look at there website www.hodgdon.com it will give you all the data you need for Hodgdon, IMR or winchester powder. Their website should also tell you who their Aus distributor is

Sport45 · May 23, 2009, 03:38 AM

I believe it's Picasso, and his art looks something like this:

So IMHO, I don't think the OP is really claiming to be an expert at reloading.

(If Picasso was alive what would his art be worth?)

butta9999 · May 23, 2009, 06:11 AM

Im changing it now....

kiwi56 · May 23, 2009, 04:12 PM

Since Hodgdons took over IMR we in NZ are able to get IMR powders as easily as Hodgdon but in saying that they are expensive and all of my rifles shoot ADI just fine so I tend to stick with that.
I am not sure if IMR powders are still manufactured in the States as The Hodgdon company tend to get most of their bulk powder from all over the world, most notably Australia
