Accurate #9 Powder
My reloading book has a load for 30 Carbine using AA 9 powder. Is this the same as the Accurate #9?
Just want to be safe.
Thanks,
Jim

Always good to be safe. Somewhere in your book it should list all the powders used in the data. My guess is you are correct. Provide your intended load and bullet for a cross check. 0 -
AA is a common short-form for Accurate Arms, so likely AA9 is the same as Accurate Arms 9. 0 -
Charlie,
Per the Speer manual, AA9 is Accurate #9.
Here's the load I'm planning on using. Mixed HS (mostly military) cases, 12 gr of Accurate #9, Fiochi SR primers, and 113gr Cast bullets with a gas check.

Lyman 49th Ed lists 110 jacketed round nose AA#9 11.7 gr 1805 fps 29,900 CUP, 13.0 gr 1935 fps 38,800 CUP
They don't have a listing for this powder using cast bullets of 115 or 130 gr.0 -
Wow! that's quite an increase in pressure for 0.3 gr increase.
My Speer book doesn't show pressures. It has 11.4 grs as a start (1739 fps) and 13.4 grs (1950 fps as the max with a 110 gr bullet.
The middle would be 12.4 grs. Since I'm using a 113 gr bullet, backing it down 12.0 should give me a margin of safety. Oh, and I'll be using a Lee factory crimp die too.
Once I get the load I want to use, I'll be making the final adjustment on the Lee 1000 turret press a neighbor gave me and crank away.0 -
I think its 1.3 gr or about 10 %. My dad liked the Lyman 311359 bullet for carbines. You need enough pressure to cycle the action reliably IMO after that its what the rifle likes. 0 -
Thanks Charlie.[:D] 0 -

I would reconsider your starting load. The 1st edition of the Lee reloading manual. Shows a maximum load of 11 grains of AA 9. With a 120 grain lead bullet, @ a muzzle velocity of 1769 FPS.
My experience with the this Lee 1st edition. Has been, a lot of their loads are right on then red line. If you know what I mean.0 -

Rufe,
Thanks. You saved me from a high pressure problem. While I don't have the Lee book, I googled Accurate Powders (should have done this along with looking it up in my book). I found the following for 30 Carbine and #9 powder:
110 (L) LC RN 11.0 1,792 12.3 1,959 45,450 1.680
115 (L) LYMAN #311359 10.0 1,678 11.2 1,834 45,028 1.635
You saved me from a high pressure load. Now I'll start with 10.5 gr. This will conserve powder too.0 -
The gentlemen over in the reloading forum are always asking me to kick some threads their way. Since this one is close to the mandatory lock at ten posts I am going to move it over to them. 0 -
I tried the #9 on the lighest load for my carbine. Would not cycle. Also the primers were backing out. Then tried some hotter loads in the blackhawk in 30 cal carbine. Worked Okay but again the primers were comming 1/2 way out. Must be a real pressure spike. Went back to H110 which works fine. Just gave 4 pounds of the #9 to a buddy that loads for .357. Seems to work for him. 0 -
Primers backing out is usually a sign of low pressure same, as the action not cycling. Case length is important on straight rimless at the mouth edge is what sets the head space. 0 -
Really - I just learned something!! 0 -
Good read and Interesting -Thanks! Sort of makes me wish I had not given away 4lb of #9 but it went to a good guy. 0
