After reading an article in a magazine the other day I really want to try this powder in a 338 Win. Mag. http://www.adi-powders.com.au/...uide/equivalents.asp I am thinking about chopping the barrel to 20.5" and going to a powder something similar to IMR 4350. Dick Metcalf wrote a good article in Guns/Ammo on short barrels being more accurate and I agree. This powder from ADI is supposed to be extremely temperature stable with only a 5 fps spread between really freezing, to really hot. I am going to try and replicate the results Boddington got with this brand of powder. | ||

According to both ADI and Hodgdon, AR2209 and H4350 are EXACTLY the same thing. | |||

They are very stable powders temperature wise. I use it a lot and can go from cold to bloody hot and not notice any differences. And yes, they are the same thing, ADI make the powder ! Previously 500N with many thousands of posts ! | |||

Great powders. I use AR2209 in my 7mm 08, some 280 AI loads & my 416 Rigby. I use AR2208 (Varget) for the 7mm08 & 9.3X62. "When the wind stops....start rowing. When the wind starts, get the sail up quick." | |||

In my humble opinion ADI AR2209 is the best powder for 180gn to 230gn bullets in the 338Win Mag. Reloader 17 is best for 160gn bullets and Reloader 22 and ADI AR2213SC are neck and neck for 250gn to 300gn bullets. | |||

Does all ADI powder resist temperature extremes or just the new 308 and 223 Australian Outback ammo? | |||
|
| One of Us |
I think all ADI Powders. I'd have to check the latest book for the latest info on the newer powders but AR 2206, 2208, 2209, 2213 and 2213SC which I have used were all stable in extreme temperatures. Previously 500N with many thousands of posts ! | |||

I read Boddington's article in Guns/Ammo and they placed the ammo in the freezer and in the sun. Only a 5 fps spread in velocity. I do not know if that is a special proprietary powder relegated to the "Outback" 223 and 308 ammo or AR 2209 as well. I can't think of a greater variable to address than the fps variation with conventional powders in relation to changing temperatures. | |||

ar corey I'll say it again. If it is ADI powder, it is likely to be insensitive to temperature variations. Believe me, they know WTF they are doing when it comes to making powder which is why they ship it half way around the world to you lot !!! LOL Just load it up and go and shoot it. I go from 0 - 10 degrees when loading to 40 - 50 degrees (100 - 110) when shooting within 1 - 5 days in double rifles and have never noticed it changes the POI. Sometimes the ammo gets that hot in my belt I can't touch it so it is probably more than 110. Previously 500N with many thousands of posts ! | |||

I'll confirm what 505G said. All ADI AR powders are NOT TEMP sensitive. That is not the case for their shotgun or pistol powders as far as I know. | |||

Try it at 40 below and see if you still believe that. | |||

Best country in the world.  But I do regularly hunt yours in the off-season. Can you say the same? | |||

SLR 7.62 Ammo used to work below freezing but 40 below is not normal operating temps !!! I'd like to see your rifle work at 40 below without "special" care taken before even worrying about the powder / ammo !!!  (and don't forget to take care of your "tackle" as well )Previously 500N with many thousands of posts ! | |||

Freezeing really isn't that cold, we ride snowmobiles at -40 by dressing appropriately. That's pushing it a bit, but wearing the same clothing to shoot is quite comfortable. No special care is needed to keep a bolt gun running at 40, just avoid heavy grease and accumulated grime inside bolts. With todays lubes it isn't a big deal. I have seen some combinations of mild primers and large charges of slow burning powder that were unreliable to fire at all, but that's rare. It was -32 a couple days ago and we went hunting. The wedding tackle has a completely different maintainence routine, no need to get into that now. | |||

If I ever manage to make it to the North Americas it will definantly be to Canada. It is very short on my bucket list and I'm looking forward to it. I'll definantly be loading ADI powders.  | |||
|
| One of Us |
We use them too but everything has limits. We pay half of what you get charged for the same thing though. Sort of like how we make IMR powder, sell it to the Americans and buy it back. I use ADI powder in Australia so my ammo can be loaded and waiting when I get there. Woodleigh bullets and 2209 this year. | |||

OK so that statement of mine was a bit wide. From memory only ADI powders are temp insensitive between -25C and 70C. That is temp of the powder. | |||
|
| One of Us |
That would be about right as that would be about the Operating temp of the Aus Military. I've had cases damn hot, probably over 50 if not higher and no problems. Previously 500N with many thousands of posts ! | |||

Where did you aquire this knowledge? Did you read it somewhere? I am inclined to think the extreme temp. stability would be relegated to the ADI "Outback Ammo" which is only available in .223 and .308 Much like Hornady's Superformance ammo which used a proprietary powder and was only available in the loaded ammo. That changed of course but I don't think all ADI powder or Hodgdon Extreme performs the same as the Outback ammo. | |||
|
| One of Us |
Another question. Is Varget and ADI AR 2208 the same? Perhaps ADI is simply trying to load there own ammo and are marketing temp. stablility. | |||
|
| One of Us |
Do you have a chronograph variable for this statement? I am looking for a powder that is within 5 fps of itself between -25C and 50C to hunt Saskatchewan whitetail, mule deer and moose. | |||

I once saw a warning about using double base (ball) powder at temps below -40F. It has something to do with the nitroglycerine being shock sensitive at very low temps. If you were to keep your cartridges in an inside pocket and chamber the round when you were ready to fire it should be alright. Speer, Sierra, Lyman, Hornady, Hodgdon have reliable reloading data. You won't find it on so and so's web page. | |||

"I am inclined to think the extreme temp. stability would be relegated to the ADI "Outback Ammo" which is only available in .223 and .308" ADI have been loading ammo or companies associated with them for years for the Mil. Previously 500N with many thousands of posts ! | |||

As far as I am aware, all ADI AR series powders have the same temperature stability. | |||
|
| One of Us |
I don't know about rifles or powders, but I do know for sure that I don't work in 40 below temperatures. | |||
|
| One of Us |
Agree. I can't think of anywhere the Aus Mil works with that temp. The coldest I know of is Mountain and Artic Warfare (or whatever it is called now) course up in the snow fields. Previously 500N with many thousands of posts ! | |||

I think one of you is talking in Fahrenheit and one in Celsius though, might make a difference... | |||

40 below is 40 below on both systems. | |||

Sorry I have been absent for a short time. The ADI powders have been around for a while now. The Outback ammo is new but using the time proven ADI powdwers. Varget is just rebadged AR2208. H4350 is rebadged AR2209. Jump on the ADI web site and you will soon pick all this up. The Temp range is what I read in an article published in either a reloading manual or magazine back in the 80's. Backed up by Ballisticians at a couple of Aust Defence eastablishments. I was able to view pressure, velocity, powder temp etc data at these places. No I am not one of the boffins. The AR powder used in the 7.62x51, or more correctly the Aussie issued 7.62 ammo loaded with AR powder was also tested in Antartica to ensure it would work there if needed. I can not remember what the details of the results were, just that it worked. What temp that was at I do not know. The Temp insenitivity of the AR powders has been marketed by ADI-now Thales- since it was developed. Don't know about you blokes but if I was hunting at -40 I would be using AR powder with a magnum primer. just to be sure. Just corrected a typo. Varget=2208 not 2209 | |||
