I had good luck in .40 with AA#5

Both will work well. Whoever told you Unique was not good for pistol isn't a good one to get any more reloading advise from.

I agree with Walkalong, Unique is a VERY popular powder for pistols.

I use Hodgdon's Tite Group for my 9mm, 38 spl & 357 mag.
Soft recoil, low charge weight (so it economical), burns clean & is very consistent (not sensitive to position in the case).

I use AA5 for 45 Colt.

According to Accurate's website it's good for both of your calibers

Good Luck & Stay safe

I use Unique in my 20 and 28 gauge shot shell loads.

But Unique is my primary powder for my 45 Colt loads.

I have used it with good results in 45 ACP, 38 Special, 9x19, 9x17, 38 Super.

Since I have Marlin 1894 in .357 magnum, you could say Unique is also a rifle powder.

There is a reason the powder is called Unique.

As already said, you got some bum advice about Unique.

I have good results with AA#5 as well.

For 9x19 or 40 S&W I prefer BlueDot or AA#7 but AA#5 and Unique will serve you well.

#5 is unpredictable in the .40. Accurate can't figure it out. A lot of issues have been recorded with #5 and the .40 with less than max charges. Just be careful with it.

Unique works great in 9MM loads for my pistols and carbine rifle. Only thing is that some say it doesn't meter well thru their powder dispensers? With 124 grain jacketed bullets 4.8 grains of Unique is a mild load and 5.0-5.1 is a good full power load but not quite a maximum load. Use data for AA#5 that is near a full power load, don't use very light loads of AA5 in 9MM, 40, or 45 ACP. It is a good powder but not for light loads. My RCBS powder dumper will reliably dump Unique if you operate the handle exactly with the same motion and by a slight peck of the handle to fill the powder rotor. Unique is also a good target load for shotshells and may not be the optimum powder for certain loads but it is unique in that it is a good powder for so many calibers.

o wow i didn't know that about #5 i just loaded some test rounds last night for .40 i did 6.0gr with a 180gr xtp and some 9mm at 5.5gr and a 135 copper plated rnfp i haven't had a chance to try them yet but hopefully today. every one seems to like the AA#5 what brand is this i dont have load data for it at te moment im reloading off of the lee data that came with my dies still waiting on the manuals i ordered

Everytime I read of a KB, AA#5 is in the mix.

I started using AA#5 recently for 9mm and I like it. 5.6g behind 125 LRN (SmallBall from Missouri) is the best load I've found so far with that bullet. It gave me 1069 avg fps with ES 18.46 and SD 6.24. Very accurate and very little leading. 6.1g behind Sierra 125g JHP gave me 1132 avg fps with ES 27.13 and SD 10.14, this one is also very accurate. Both were shot from CZ 75B.

As already mentioned Unique is an very versitile pistol powder. I've had good luck with it in 357 mag and 45 Colt and although it doesn't measure all that great in my Lee auto disk the slight variation doesn't seem to affect the results for me in those two calibers.

I've had the best luck with HP-38 so far in my 40

I've been using AA #5 in .40 since I started reloading a few years ago. I've used it for thousands of rounds of 9mm, .40, .45ACP, .38spl, and .357Mag. It might not be the ideal powder for each of those calibers, but it works pretty well. It flows consistently through the measure, burns pretty clean, and is relatively economical. As far as being an issue in .40, I'd like to see some documentation of that. I can't see how it could be an issue as long as published load data is used. Considering that #5 is still listed in the manufacturers guide, I'd assume they don't consider it a liability.

Unique and AA5 have very similar burn rates and occupy the same functional niche producing similar potential medium and high velocities in handgun cartridges. AA5 being a ball powder you may get better metering in some measures.

You may want to use a faster powder for more economical light loads with cast bullets. Powders like Red Dot, Promo or Green Dot will work well for those kind of loads if you happen to have a faster powder for your shotgun.

My apology for hijacking this thread, but would appreciate load data using AA#5 from you guys who use it for the .45 Colt?

Lyman #49 includes 45 Colt loads with AA#5 for all 10 bullets listed.
My experience with the 255 gr LSWC matches the Lyman data.

Maybe a new thread the 45 Colt would be a good idea.
It is hard to discuss actual loads without opeining the topic of the guns that are appropriate for them. That is far from the OP's topic.

Be Safe and have Fun !

I have loaded alot of 45acp, 38spl / 38+p, and 357 with A5 and I really like the way it meters and gives me great groups.

do u use a rcbs uniflow powder measure??? i have a lee perfect powder measure and the powder is leaking out of the side where it turns dose anyone know if #5 is too fine for the lee??

AAC#5 and Unique are both truly excellent powders for 9MM and .40 (.38Spec and .45 ACP as well.)

Don't push them too far though. If you ever want higher velocity/power you'd be well advised to switch to a slower powder like HS-6 (my favorite) AAC#7, Power Pistol, or Herco.

There are some comparable powders from VV, Ramshot and a few other manufacturers available, but I've been so well pleased with HS-6 over the years, I've never been tempted to try them. :D

We are in total agreement there. I'm a big fan of HS-6 too...

CAUTION: The following post includes loading data beyond currently published maximums for this cartridge. USE AT YOUR OWN RISK. Neither the writer, The High Road, nor the staff of THR assume any liability for any damage or injury resulting from use of this information.

I have done lots of experiments to try to blow up guns in incremental work ups.

If I just overload them, and they blow up, I don't learn much.
It is like an engineering professor told us about radial tension, "If the rocket blows up on the launch pad, you don't learn much."

Anyway, after thousands of such work ups, it is my opinion that if AA#5 won't blow it up, nothing will.

That is, it has the highest speed - density product.

That does not mean it will necessarily blow your gun up, unless you put too much in.

Where Power Pistol will just make a bigger and bigger fire ball when more powder is added, and so the effect of each increasing charge is small.

But AA#5 is peaky, and a small change makes a big spike in pressure.

Of all the pistol cartridges with small safety margins, an old Glock 40 S&W or an old Glock 10mm have got to be the ones closest to the edge.

So if you combine worn out old brass, an old Glock 40sw with terrible case support, some handloading technique variables, and AA#5, I can see a kaboom might happen.

On the other hand, with decent brass, and old Glock, and being careful with those AA#5 charge measurements, I can imagine a million rounds with no problems.

This is in contrast with Unique and 115 gr in 9mm, where a screw up bad enough to make real trouble just plain will not fit in the case.

What does it all mean?
If you use AA#5, don't screw up on the powder charge.

"Don't screw up on the powder charge." :D:D:D

Clark, "you da man!" :evil::evil::evil::evil::evil:

Seriously, thanx for that info. I wasn't aware of it before! :):)

For 9mm and .40 S&W you can't go wrong with Ramshot Silhouette. Much like HS6 but treated for muzzle flash.;)

I have had very good results with AA#5 for 45acp, 38spl(upper end loads), 9x18 Makarov, and reduced .357Mag loads.
I tried AA#5 as a replacement for Unique because of metering issues. I don't load for the 40 S&W so I can't comment for that.
