AA #9 for a 9mm load?

[Wildbillz]

Hi All
Anyone use AA #9 to load up 9mm? I saw in my Speer manual that they list it starting at 9.4grn (1061 Fps) with a 124grn Fmj bullet. I have about 10 lbs of AA #9 that I got in a deal a few years back and the only thing I use it for is 44mag and I don't load a lot of them. If I could use some of it up to do 9mm (which I shoot a lot of) it would be nice and make for some super cheap loads.

So anyone used it in 9mm? What sort of results did ya get?

Thanks
WB

The Accurate powder reloading data center doesn't list AA#9 as a 9mm powder. Not that it can't be used, I just think you'll have case volume issues with that much powder.

#9 is a very slow powder more suited for magnum cartridges such as heavy 357's. it's actually slower than Blue Dot.

I doubt you will get it to burn clean at all and you will have case volume issues as Chris stated.

AA7 is about the slowest powder I would ever put in a 9mm and it's even almost to slow. I've read posts on here about members that tried to load heavy loads of AA7 and bulged their cases creating chambering problems.

If you did use AA9 it would burn really dirty from lack of pressure from being to slow.

I agree with Tiger about the case being too small to use #9 effectively. I disagree about #7. I love AA7 in full power & +P 9mm loads especially 115g JHP's, and I use #5 for lead practice rounds 115-150g SWC's. The AA load data has changed a lot to make it lawyer proof. It was much higher when I first started loading 9mm in the 90's than the loads listed the latest guide

Love AA#9 in 38 super and 10mm. It is kinda dense but not sure it will fit in 9mm. I have lots of AA9 and simply have never though of using it for 9.

Fill the case up to 100% load density with #9 powder and see for yourself?

It'll either cycle the action or it won't. Your sure can't over charge it.

No harm trying. I bet it will work.

Perhaps. But I would rather save it for super and ten loads. Titegroup and hp38 are for 9mm.

Since it uses a good deal of powder, I don't think it will make for a cheap load. But as loads go, it's a good powder for high end high velocity loads, it's designed for such. It's not at all difficult to manage pressures with it, it's not touchy during work ups like faster burners are. It functions best when used at higher charges, above mid level in other words. So don't try to reduce it to below published data in an attempt to tame it to target load level. I like it about as much as Longshot for full house 9mm, .40, and 38 spcl., and I'm sure it will do well in a host of other cartridges too.

It may take a lot of powder, but I have like 10 pounds of it that was tossed in with a deal on a bunch of reloading equipment I bought. So its a $0 cost to me.

I don't know that you can get enough of that powder in a 9mm case to get it to burn properly. Max loads with it in 10mm are sometimes compressed loads, and that's a much bigger case. If the load data is to be believed, it's not suitable for .40 S&W, which just has less case room and a slightly lower pressure limit.

I played around in 10mm with using it for reduced loads... it didn't do anything scary, but it got very, very dirty. I switched to AA#7, which also happens to be useful for 9mm.

Since you have data for it, just try it and let us know how it works. Don't need to load up a bunch of rounds just to try it out.

 

[beatledog7]

AA#9 is a very good 357Sig powder. I'd never use it for 9mm since faster powders are so much better for 9mm.

With all the issues that you face using this really slow powder for 9mm, I would try selling the AA#9 and buying something more compatible. With the scarcity of powder right now I'm sure that you could find someone to buy it.

Just my .02

Ya, its not sounding like much of a match. I will try a few with the Speer info and see how they go. If nothing else I have enough powder to load 44mags for the rest of my life.
