Accurate #9 and 9mm?

[Seedtick]

Greetings Ya'll,

Have you ever used Accurate #9 in 9mm? I found a recipe in both Speer 12th and 13th edition reloading manuals.

The particulars are -

125 grain Jacketed bullet
1.135" overall length
Accurate #9
start 9.4 grains
max 10.5 grains compressed



I would have thought it was too slow for 9mm but maybe not.

Number 9 is my 2nd favorite powder in 357, behind 2400, so it would be handy if it was the bees knees in 9mm.

If you've tried it please share your thoughts.

Thanks

ST

Accurate doesn't list any loads with AA #9 in their latest online PDF file. That tells me it isn't the best choice. I have never tried it though. AA #5 works great in 9MM, and lots of folks tout AA #7 in 9MM, but I have never heard of folks using AA #9. I like AA #9 too, but never considered trying it in 9MM.

AA9 can certainly work, but it won't be at it best. You would be much better off with AA5 or AA7. AA7 is excellent in 9x19.
What you have there is the ONLY LOAD I have seen for AA9 and a 125gn jacketed bullet in 9x19.

Judging by the speed, it would make an OK "slow" powder for use with 147gr bullets. "OK" but not "great". Probably way too slow for 124gr.

I wouldn't try using AA#9 in the 9mm. As said above AA#5 or AA#7 are much better choices. I'm a big fan of Longshot in the 9mm and since AA#7 is really close to Longshot on most Burn Rate charts I'm guessing AA#7 will work well for full power loads. For practice ammo AA#5 would be my choice of the two although I usually use W231/HP-38 for 9mm practice ammo.

I would not use #9 because I don't crimp and with a slow powder a good crimp is more
important.

I like AA#2 best for 9mm. Takes less and burns cleaner. May not give you the highest velocities, tho.

I might try AA#9 in a 9mm if I had a 9mm carbine. The longer barrel may give some use for the slow powder. For handgun I don't think I'd every try it unless it was the only powder available that I could find data for.

Thanks for your replies, Guys.

I normally use Power Pistol or HP 38 for my 9mm loads although I have tried a few others.

I may load up a few just to see. You know, the variety and spice of life thing.

No taper crimp? I would guess that you don't bell out your case to accept the bullet either? Man your size die must make them a "Perfect Fit"??
Myself I: bell the case-seat the bullet-taper crimp the case.
AA-#9 powder is less than desirable for use in any 9MM load.
Yes a good-firm ROLL crimp is to be used when using AA-#9 in Magnum REVOLVER loads.

billybob44 - Sometimes I bell them and sometimes I don't. If I bell them I use the Lee taper
crimp die with no crimp. Without crimp it takes out any excess bell to ensure round fits chamber.
I have never had any luck with taper crimps. I always roll crimp revolver rounds and have had
good luck with them.

AA#9 = Ramshot Enforcer = H108 = WC820

It is not really compressible with Copper jackets lead bullets. The bulk modulus is so high, the bullets will squish.
