What's a "fluffy" powder for reloading 9 x 19, 125gr boolits?

[EDG]

You don't want just a single characteristic called fluffy.
You want fluffy and the right burn rate at the same time.
Fluffy can be defined as the specific gravity of the powder. The LOWER the specific gravity the more space a grain of powder will take up in the case. Specific gravity is the mass of the powder per CC compared to water. The specific gravity of water is always 1 - that is 1 CC of water always weighs 1 gram.

Pick all the powders with the right burn rate to produce the best ballistics.

Then order the powders from the most dense to the least dense.
Measure the volume of your case to the base of the bullet.

The least dense powder with the right burn rate that fills the case would be ideal.

Use a loading manual to give you maximum charges.
Pick out a fluffy powder and see if the max charge fits. If it does not fit go to the next more dense powder on the list.
I used this method for picking a powder for the .45 ACP and wound up using HS 6.

WST is good and does a good job of filling the case.
For light bullets in the 9mm I have been using Titewad(not Titegroup). It uses very small charges(2.9-3.4gr), burns very clean, and measures consistently. Even the small charges do a good job of filling the case to prevent double charges in 9mm.
You will not get max velocity with this powder but I get good accuracy with it. I mostly use it with 95-105 grain boolits where it is superb.

I have used IMR 700x with good result in 9mm , although, it does not make power factor in my application, it does reliably function my gun and is generally soft shooting. It does not meter well for small charges in my Lee perfect powder measure so I dip to ensure a bit of consistency. For power factor loads I have been using HS-6 ( similar application as WST), it's not fluffy , but meters like a dream and makes power factor with little effort.

700X works well for me in this application. Plenty of volume in the 9mm brass with appropriate loads.

The best results I have had with a 9mm have been with W-231 or HP-38 (identical twins).

Herco! Light charges almost fill the case, heavier ones are compressed loads. A max load will not fit into the case.

THIS...........you see all the guys advocating Unique....that's because they've never used Herco, which is in between Blue Dot and Unique....Herco does/will do anything Unique can just a bit better...."generally" it will take about 1gr. more of Herco to match Unique pressure but you'll gain a bit more velocity....it wasn't THAT many years ago that Herco was THE go to powder for the 9mm luger....

AA #7 is another powder that will fill a 9X19 case.

Bullseye also won't double charge a case but, you can overpressure the 9mm. I use a load of 3.2 grains because I've been up the scale, no reason to increase it. At a point it gets too hot.

[oldfart1956]

I had it firmly stuck in my mind that in order to simplify life I was going to only use 2 powders. Unique and Bullseye. I can...actually. I figgered that way I'd just buy 8lb. jugs and life would be swell. Unfortunatly (or not) it hasn't worked out that way. I tried fluffy. TrailBoss. I can't get it to work consistently in any of my powder measures. ( Lee perfect/Auto-Pro and a Lyman 55) Some folks can, I can't. I don't have the time or patience to dip out powders and weigh each charge with pistol rounds. It has to go thru the Auto-Pro on the turret press. And it has to be consistant as checked with the chronograph. Bullseye did well...very well. Unique works puddy good as long as it isn't small doses. Above 7 grains...not an issue. Recently started working up loads for the 9mm. and one powder easy to find (and affordable at $19 per pound) was TiteGroup so I just hadda try it. Very consistant, no sticking or bridging and the chronograph showed every round running between 1050/1075 fps. This is the 9mm in a 1911 with the Lee .358-125 rnfp resized to 356 with an O.A.L. of 1.060. At the starting load you could double-charge a case but much above that you'd play hob getting a boolit seated without bulging a case. The downside of TiteGroup is there's a small window in which it works. For the 9mm. it is starts at 3.4gr. and max is at 3.8 so pay attention. That's with my boolits and oal so check your numbers. I also ran TiteGroup thru the .45acp and 24 rounds over the chronograph had every one between 777/780fps. That's a very consistant powder. I'll never give up Unique or Bullseye (too versatile) but I sure am impressed with TiteGroup. Audie...the longwinded Oldfart..

Going for "lower power" 9mm loads for 3-Gun shooting, for my son. I'm looking for a some "fluffy" powder to avoid potential double load hazards. I'm using Trail Boss for my 45LC CAS shooting, but that's the only powder I know of that is 'safe' in small amounts. I'm guessing a 9mm will take about 3-4gr, but that small amoiunt is hard to see in the case whilst reloading. Thanks for watching.

Wally

Is it just me, or did many of the responders above lose track of the OP's goal? He wants a very soft shooting round that fills more than half of the case. Wally, I have NEVER reloaded 9mm, but IF a charge of Trailboss that fills the case to the point of just failing to compress the powder will cycle the action consistently, then you have your load. Is it going to be the most accurate load? I highly doubt that; but at least plink worthy and definitely soft of recoil and report. I do that exact same thing with 40 S&W and it works great and is plenty accurate for plinking in my Glock 23. That powder is almost white of color and very easy to see. Just fill the case to where the boolit base will touch, but not compress the fluffy stuff. Try a few rounds, if it cycles you have it made in the shade with a powder you already have on hand. Herco is a great powder, but where are you going to find any to buy? When I tried this doughnut like powder, I "knew" it would be lousy of consistency in the powder measures -- I was wrong. In my Pro-Auto measure it drops very consistently.

I use 4.5 Unique under a 124 Lee TC with any case or primer loaded to 1.060 OAL for my plinking load. It works well in all 6 of my nines AND makes PF for IDPA as well!

[hometownhero]

Sorry to bring up this old thread but...

I use unique right now for 9mm. Love how it fills the case. I would like to find something that I can actually get more then once every 5 years. So something in the hodgdon lie would be great. What would compare in case fill to unique? I have some titegroup but case fill is no place near what I would like. It sure is accurate though. Making max power doesn't really matter for me as in Canada we can only target shoot our pistols at an approved shooting range.
Suggestions???

[Greg S]

I mainly use Unique but Herco is very similar. Actually had better accurracy with it.

[retread]

During the last "shortage period" I could not get my usual choice of powders but Grafs had plenty of Vectan powders. I bought 8 lbs of Vectan AS. It is "light and fluffy" but does not jump out of the case when indexing the Dillon 550 like some other powders (ETR7) comes to mind. You will definitely notice a double charge. It would be hard to miss.

[Ole Joe Clarke]

Unique is a good choice, so is Herco, Green Dot, and so on. I've never had a problem finding Unique, have and use more of it than anything else. It's an old (like me) powder that works. I like the saying: "If it ain't broke, don't fix it."

Have a blessed day,

Leon

[farmall666]

I use green dot works very good in my ruger SR9C

[hometownhero]

So no Hodgdon powders really? Alliant is very hard to get here in Canada. This unique I have now was some of the first Alliant powder we have seen since obuma got elected the first time. Hodgdon is pretty much always available someplace

[Mytmousemalibu]

I'll second Vectan AS, its great for lightly charged 9mm and the powder is cheap and available. Bonus their 1lb containers are sold as such but are actually 1.10lbs so you get a little bit extra. Overall low price and its really great powder. Im also loading 9mm with Ba9 and Ba9-1/2. The AS is a large trapezoidal flake powder and the Ba powders are short extruded stick, too big to leak, fine enough to meter like sugar. Never had metering problems with any Vectan yet, no leakage. The Ba powders meter very nice, doesn't sling out of the case while indexing.

Don't get that in Canada.

I'll probably get flamed hard for this one but while "fluffy powder" is one way to "skin a cat" of potential overloads.....proper loading techniques and checking would seem to be the proper answer...that way when powder get's tough the loader is properly schooled in the right loading methods and can concentrate on loading what is available.

I load Trail Boss on occasion...Unique for years..etc but there are many times another powder makes for a much more effective load for what I'm intending to do...a simple example would be a 200 grain LRNFP (coated) in my 45acp using W231 (load density is in several places so I won't list it here)...it's a load that meters great, is accurate in my CZ 97, is nice shooting and simply does exactly what I want..I guess I could double load or overcharge but so far (and I never get cocky) I've been right on with it for some years now.

I just think the use of "fluffy powder" can sometimes be used as a safety valve for poor loading technique and I am personally opposed to that..
