I have burned a fair amount of it

I like it in the 357 Mag for top end loads
I use it behind a 180 gr cast bullet (that I cast) for deer sometimes
IMO it isn't a powder to try with reduced loads , stick with published loads
I have never worked up any loads for the 44 mag with it .......yeat
I also use it in the 454 for deer loads with the Lee 300 gr GC bullet mold


Only bad thing with it
Some powder measures bind up with AA#9
As it is so fine

I've used it with great success in .44 mag handloads & .500 S&W handloads.

Good powder for those applications for sure.

Accurate powders are among my favorites, I've been a fan of theirs since they first started importing them. #9 is a good choice for full-power loads, cast or jacketed. When it comes to clean burning and excellent metering there are few powders that work as well. As was mentioned, #9 is not a powder you'd want to use in reduced loads, but it's a lot less finicky than H-110/WW296. I'm not a fan of full-power casts loads until gas-checks are involved, but if so then you should be able to get some pretty impressive velocities, especially out of a long barrel.

 

I love ACC#9 in my 1894C and my S&W 19-4. I use it for a full power load in both with the Lyman 358156 SWCGC bullet. My alloy produces a bullet weight of 164 grains with lube and gas check applied. My load of 15.0 grains and a Remington standard small pistol primer produces 1800fps in the 18.5" barreled Marlin and 1368fps from the four inch S&W revolver. That load of ACC#9 is the most accurate load developed in both firearms and I'm a happy camper. Not too often does one find a load that is the most accurate in both rifle and handgun. It is a TOP end load in both rifle and revolver, so work up carefully and judiciously watching for any signs of pressure. My lot of ACC#9 and my lot of Alliant 2400 produce the exact same velocities, grain for grain, and I use the one that produces the best accuracy. Alliant 2400 works best with my Ranch Dog 357-175 bullet that weighs 180 grains fully dressed.

Since the shortage began,2400 and Unique are MIA here,as are all Alliant powders. I have been using AA#9 in my 44s,the supply is good so far,and now I'll never go back to 2400.The charge weights are the same,the #9 burns clean,velocities are the same,and accuracy is great. Here's the kicker-- after shooting #9,it smells like the .22 ammo of my youth. I'm instantly transported back to those wonderful times. It's like cleaning with Hoppe's,or Mom's apple pie baking when you got home from school. Old age is funny.

Thanks for all the input guys. I'm always looking for alternate ways of doing what needs doing. I've found in the last few years the necessity of learning to adapt and improvise quite a bit more than in the past.

 

#9 is my go-to powder for .357 full power loads. As was stated, it's burns cleanly and meters quite well. Also, it doesn't require Magnum primers and produces very little muzzle flash, making it great for low light situations. I use 13.5 gr under 158 gr cast bullets from Dardas, sized at .359". I try to get CCI primers but here lately I use whatever I can find. I'm told it doesn't do well with reduced charges or with light bullets, but I cannot speak from experience.
As far as velocities go, I get mid 12's from my 4" revolver and high 17's from my 1894 with no leading. Being a slower burning powder, I don't imagine it would do as well with short barrels.

Another AA#9 user here.

Have used it for a number of years in my .44 BlackHawk Hunter, and since then in my RedHawk 5.5".

In the RedHawk, 19gr put a 310gr cast bullet out the tube at just over 1300fps.

Now, I have had my supply of #9 for some years, still working on my supply from an 8lb. jug, so my load developed back probably over 10years ago, might not be safe with current powder lots.


AT the time I started using the #9, I was developing loads for the BH Hunter, and the #9 just seemed to provide better results the the H110, 296 or 2400 so that is why I bought an 8lb jug.

Now no more then I shoot the .44 these days, that supply may out last me.

I have used AA#9 in my 44 Mag Rossi Puma with excellent results. I used it with 240 gr jacketed bullets and 240 gr cast bullets with gas checks, and it was very accurate with both. The only problem I have, is that nobody in my area carries Accurate powders and I have switched back to H110 and 2400.

I'm hoping for those same excellent results in my 20" Rossi 44 mag. This afternoon my son wanted to go next door to his house and pop off a few rounds and I took the .357 rounds I had loaded with 12.2 gr of AA9 and my SP101. I am certainly pleased with that load. Not sure about velocity, or even accuracy (shooting at 2" targets about 25 yards across his little pond), but they certainly felt like "medium" magnum loads, very little smoke, absolutely no leading (Bayou Bullets), and very minimal powder residue. I shared a few rounds with him to try in his recently purchased GP100 ... now he's going on a mission to find his own supply of AA#9.

I think I have another favorite powder to add to my growing rookie list

 

GH1's 13.5 grain charge behind a 156 grain LSWC was the most consistent load I chronographed when I loaded a few for him last year. I've since settled on 14.0 grains for 158 grain JHPs for one of my trifecta for those bullets - 13.0 grains 2400, 16.2 L'il Gun, and (now) 14.0 grains of AA#9.

 

AA#9 is my primary magnum pistol powder. I look at it as a ball powder version of A2400, so anywhere you get good results with 2400, you'll likely get them with AA9. Also like 2400, it won't get that last 100-200fps of velocity that 296/110, and the other super-slow pistol powders get. I really like it's fine-granules, because they make it compact enough to get a lot into the 10mm Auto case, which causes it to work in that cartridge much like 4227 works in 44 Mag. - You can't get enough of it in the case to go over pressure limits, yet it provides top velocities. Since it gives "strong" (but not that last 100-200fps) performance in the 357 & 44 Mags as well as top performance in 10mm, it is a "must-have" powder for me...

 

I Doubt that the other powders mention in MMA10mm's post are going to get much if any more velocity then the just over 1300fps I am getting with a 310gr cast from a 5.5" barrel in my RUGER RedHawk. Of course, my lot of AA#9 is 10 + years old, and maybe there have been some changes in the powder. My findings to this point, point to the #9 being close to or equal to the H110/296 or other good slow burning powders suitable for heavy Mag. .44 Remington loads. Crusty Deary Ol'Coot

 

Crusty,
My old lots of AA9 burned like that too. My "middle-aged" lot burned as I described above, and the newest jug burns even faster - about 1.0gr lighter for a max load in 44 Mag. I was surprised by that, and went to Western Powders online load guides, and indeed they've cut back the max loads listed for "new" AA9. A good lesson for me in using up-to-date data...

 

Another vote for AA#9!

 

AA7 and AA9 both work well for me.

 

Keep an eye on Natchez Shooters Supply.

They haven't rasied prices to the ridiculous level yet, and they often have Accurate Powders in inventory. This is changing a bit though, as I suspect many have discovered AA's and they have an excellent selection of very good powders.

 

I can't afford to buy enough powder at a time to justify the hazmat and shipping charge .... gotta spend my money on silly things like ..... DOVE SEASON
