Anyone Use Accurate No.7?

[35 Whelen]

A few years ago I picked up a jug of Accurate No.7 at a gun show for a really good price. I've used it some in 357 loads, but not much. Anyone use this powder for cast bullets? Rifle OR handgun?
Thanks,

AA-7 is THE powder for the 30 Luger and 30 Mauser/7.62 x 25 Tokarev, cast or jacketed. It also does good work with higher-end 32 Magnum loads and with top-end 125 grain 9mm Luger loads, again both jacketed and cast.

i use AA7 in the 460 rowland with a gas check cast boolit on 235 gr of WW comeing out of the 1911 at just under 1500 fps. steve k

I use it in the 460 ROWLAND out of a Clark Custom 625. It can be a handful when loaded up.

Thanks for the replies, guys. What about rifle use? After posting this, I found a burning rate chart and saw that No. 7 is between Herco and Blue Dot in relative burning speed.
Thanks again,

Like to read more about this R-7 use. I know its used in the 45-70 case but what about smaller cases that were also black powder like 38-55 and 40-65 etc. any good there?
Is there a "rule of thumb" with R-7 like with 4198 where 40% equals black?

Have quite a bit of R-7 on-hand and would like to use up.

Greetings I have used it in 41 mag... upper velocity with 210-240 grain plain base. I do not have my load book down here on that caliber... burns clean and nothing peculiar that I remember.
Do not count on it for SLOW FPS shooting.. I tried that ONE TIME in 44 Russian... hang fires.. incomplete ignition... lodged a boolit in the barrel...

My uses of AA-7 are in the higher-pressure handgun venues--not in "2400/296 country", but just south of there--25K to 35K PSI in smaller case sizes.

I read somewhere (not recalled) that the original-source AA-7 was specifically designed for use in the 7.62 x 25 Tokarev, and there are variants out there with the same performance characteristics. I bought some ChiCom "#7" from Bartlett's a few years ago, and it behaves just like AA-7 once loaded into cartridges, all right--but getting those hockey-puck granules through a powder measure is an all but impossible feat. I bought a set of the Lee Loader powder "spoons" to enable something to be done with that stuff, and in 357/41/44 Mag mid-range loads it has done surprisingly well. I was a little hesitant about that whole Lee Loader spoon bit, but the things actually measure pretty consistently when used per the instructions.

The Accurate Arms AA-7 is a small-diameter spherical powder, and runs like water through my RCBS Duo-Measure.

Rugerman, GREAT use of pic posting. You may have prevented a problem for someone. Good on ya.

Reloder-7 is very close to IMR/H-4198 in my uses of the stuff, which hasn't been real extensive. I haven't tried the Ross Seyfried "40% 4198 conversion" for black powder using Reloder-7, but it is a very close approximation using IMR-4198.

Accidental use of AA7 in place of Reloader 7 will definetly disassemble your rifle. Don't ask me how I know. Neil

I have some load data using AAC#7 in the 30-30. I have been tempted to try it. The reason I am hesitant is due to the density of the powder. I don't believe it adequately fills rifle sized cases. I believe positioning would be critical. Until I find a breech block the size of an eight inch howitzer and I can pressure test these loads I will continue to avoid them. Just my two cents.

Did I ever read the title post wrong! I do know the differance between these two powders; R-7 and AA#7. Thanks for alerting me, should wear my reading glasses more often. Making oneself feel stupid can often jog the mind and again, thanks for the heads-up everyone.

Shucks it happens, better to feel stupid than to pull the trigger.

Works well in 10mm Auto, all bullet weights. I also have used it for +P 185gn 45ACP loads, but got lots of flash. S/F....Ken M

I use AA #7 for my 32 H&R in a Marlin for Pistol cartridge Cowboy Rifle. 6.3 gr behind a 88 gr GC bullet

[weakhand luke]

I use 9.6gr in 357SIG (124 cast boolit). Indoor range has a 1200fps limit, these clock at 1190.

[400cor-bon]

I use it in the 400 cor-bon loading
plan to start using it for the 357 and maybe 9 mm
published data is available

FYI


If one mistakenly uses AA #7 in place of Reloder 7 in 7.62 X 39 it WILL wreck the gun and possibly kill the person shooting it. Believe me, I know.
Not sure how to post pics here, but if you PM your email I can send detailed pictures of a Mini Mauser in that caliber destroyed by 23.4 grains of AA #7.
Double check every thing you do, folks.

Kendog,
The easiest way to post pics pn any forum, is to open am account at Photobucket.com (it's free). There, you can upload pictures from your computer, and then insert them into posts like this:

...just by copying and pasting the image code from Photobucket. It takes mere seconds to do this and is super easy.

Thanks.
Can I put them in a folder there and put a link here? Its a huge file.

Yes Ken. Once there, at Photobucket.com, you create your own albums and name them as you wish. For example, the above picture is in an album I named "Enfields". I have albums for hunting pictures, pictures of targets, Mosins, etc., etc.

No need to link it. Once the photo is upload, you go to the picture, rest your pointer on the picture, at which time a menu will appear under the picture. You then left click on "IMG Code", which copies the image code. The image code will look something like this:

.http://i60.photobucket.com/albums/h6/308Scout/Enfields/MaltbyEnfield16.jpg

You then paste this code in the post where you want the picture. Violá!! When you submit the post, the picture will be there!

Also, if you're having to deal with huge files, I might suggest you download a dandy little (1.25MB) program called IrfanView. It's free at IrfanView.com, and very simple to use. It's the only program I use to downsize photos and it will perform a plethora of other tasks on photos. It's so easy, even my 74 year old, computer challenged father can downsize pictures with it.

Good luck!
