AA # 5 and 9mm

[JO JO]

How well does aa#5 work for 9mm and 125gr coated bullets my lgs has some aa#7 and aa#5 in stock along with cfe pistol ,
using for paper pouching target ammo ?
I know there are other powders that will work but these are the 3 available to me at this time

The last shortage I used #7. It’s ok. But I prefer BE86 and Win 231.

 

[CQB45ACP]

For 9mm I only use #7 (but I also only use 115gr)

I like #7 for 135 gr and up for shorter barreled 9x19, for 124 gr in a short barrel #5 and BE-86 works well for me.

Go to the Western Powders loading data site

(I hope the link works as I’m on my phone).

There is data for both Accurate 7 and Accurate 5.

For paper punching, I’d probably use Accurate 5.

FYI, my favorite powder for 9x19 is True Blue.

I have only used AA#5 and CFE-P powders. I can't say nothing bad about #5, I just prefer CFE-P, or Silhouette for 9mm JHP target.
I do like AA#5 for some 45 Auto FMJ loads though.

 

[Dudedog]

Never used AA#5 but it is about the burn speed I like for most 9mm loads.
CFE-P has shot well for me with plated and jacketed, but I haven't used it with coated.

They all work for 9mm.

For #7 you will probably want to load very near (or at) max or you will have unburned powder.

All three powders favor loading full power ammo, not downloaded.

#5 for 147 gr 9mm. Works like a champ....

 

[rfwobbly]

No.5 is the best of all listed if your intention is target practice.

No.7 if you were loading some JHP bullets for self defense loads.

 

[packetloss]

Yup, of those choices, I'd recommend #5.

 

[Walkalong]

AA #5 is always a good choice for 9MM, unless you want to download it a little.

I have never had unburned powder.

Yep.

#7 was pretty much designed for full-tilt 124gr 9mm. Dense powder and small case. It does a very good job at it too.

#5 is perfectly capable of slightly less than full velocity 9mm. And, it's a ball powder that runs very easily through a measure (as is #7).

Either is a good choice.

Good thing I didn’t know 7 was designed for bigger loads and bigger boolits cause I’ve been using it with 115s and the lightest load since I began loading. (Don’t know the emoji for sarcasm)

AA #7 likes full power loads in 9MM, doesn’t do as well download, similar to how HS 6 behaves. It will burn much cleaner and perform better at max, which is why I always recommend AA # 5 over it for general 9MM loading.

Now, if you want full tilt boogie.......

I didn't say that #7 won't work for different loadings, just that it excels at doing it's designed task.

I've seen people use screwdriver handles for hammers. It works, but a hammer is better.

Crescent hammer, sir!
I just worked up a really nice load for Acme 125 RN-NLG with Unique, but that doesn't help at all.

As I said, sarcasm.
