I know it is not ideal for 9mm but does anyone have a safe 9mm load using A2400?

I have never heard of such a load.

I don't imagine it will even work, I doubt it will cycle the action. Why even think of such?

Where we go one, we go all

I have loaded a lot of slow burning powder in the 9 mm, when I
first got my C9 3.5" pistol.

Blue Dot was the slowest that would give me the highest fps or
lower than Unique, depending on the bullet weight and the
case volume at hand and the OAL that was available.

SR4756 and HS-6 powder fell into the same pit fall but did have
some good loads and also some that were not so good.
You just need to see if you want a target load or a +P for the pistol.

I even loaded a 124 gr "Ball" with a long OAL of 1.165" with a compressed
load of IMR 4227, that went across my chrony at 701 fps.......
and out of five loads, I also had 2 "stove pipes".

Due to the slow burn rate of Alliant 2400 and "Steel" powders,
I have found that they do not perform well in the little 9 mm case.

I also don't use 2400 in my short 38 special cases...........
since there are a LOT of faster burning powders that will get into +P
speeds with half the amount of powder and the BG will not know the difference
if hit with a bullet going 46 fps slower, when you reach
the speeds of a +P load, any way.

I save my 2400 for the .357 or larger loads, where it works best.

Thanks, I am only considering it because I can find no powders locally that are good for 9mm and I no longer shoot magnum loads. I have not exhausted the internet but Midway and a few other sources are all out of stock with no backorder taken on the other powders I would use.

Don't waste the powder. It's not suitable for 9mm. If it worked at all, it would be more of a stunt than something with a practical use.

Back in 1998 Alliant did not show 2400 powder for the 9 mm but
did had Blue Dot data, so your 2400 powder might be doable in loads
but it was not the best choice, per the Alliant company.

If you have no other choice, I will tell you that my Blue Dot loads did best with the 115 & 124 gr. Gold Dot bullets in my C9 3.5" pistol with a OAL of 1.12", that offered more case volume , than a "Ball" bullet design.

The main problem with extra slow powders is the case volume room that is at hand when a bullet is seated.
Even the old stand by Unique powder, will have problems finding FPS, when you seat a 124 JHP with a OAL of 1.075" !!

2400 powder should work for light target loads and even a standard load if you get lucky, with a long OAL.

Maybe a 7.5 gr load with a 115/124 JHP for starters, to see if it has enough energy to work the slide........?
Hopefully, you can find some data on this idea.

Stay safe.

Just yesterday I searched around on using 2400 in the 9mm and 45acp, and found general disdain for the idea. I wanted some for 38/357 loads and wondered what else I could do with it.

Decided to buy some anyway, and at my LGS the last pound had just walked out the door... along with their last 8lb of Unique. So zip for moi.

If you want to sell it on, pm me.

Look through some current load manuals. I would guess there are a number of less popular powders that may be in stock at shops or available online that would work far better than a completely unsuitable powder. We have a glut of powders today, many of which are virtual duplications of something else.

Check with Hodgdon's web site , I got an E-mail that read "High Quality Powders Direct to you" ... from what I can tell ...they will help you find the nearest dealer with the powder in stock and have that dealer ship it to you ... Hodgdon shipping powder directly to an individual doesn't seem likely ... I didn't start the "Shop Now" process so I maybe wrong ... but at this point and time any help finding powder would be helpful . Check into what Hodgdon's trying to do ... it may be a help .

Decades ago I tried loading .45 ACP with Blue Dot. It worked the gun, but accuracy suffered and I ended up covered with little flakes of Blue Dot. Best stick with powders that match the cartridge you're using.

While there are no primers and not a lot of powder in stock around here the local Bass Pro does get some powder in. I saw some 700x there last week. I didn't buy it as I have enough. You might check them or similar even if you have to drive. You can try and check ahead to see if it is in stock at the store. As high as the prices are the powder prices there are not to bad.

I know a guy that loaded 748 in some. It smoked worst than black powder but we got a good laugh.

Always use a current loading manual for ANY LOADS...........If you value your fingers and eyes..........NEVER load an "internet" load. Always verify with a Current loading manual.

2400 has too slow of a burn rate for the 9x19 cartridge. The 9x19 is a small capacity cartridge and not suitable for the slow burning powders that work well in 357 Magnum or larger cases. You really need powders with fast to medium burn rates, anything from Bullseye and HP-38/W231 to Unique, Blue Dot, HS-6, AA#5 work well.

I have some OLD load data for 296/H110 powder in 9x19, but I wouldn't publish them. Nothing for 2400.
Very slow powders like that can't really get up to "working temp/pressure" with so little volume. Don't know why, but you can see it with 10mm Auto, where AA7 and AA9 out-perform 2400 and slower powders, and that isn't even a really small case like the 9x19.
2400 should be a better bet than 296/H110 (it, at least, has no problem igniting at 9x19 pressures), but back then, 296/H110 was the NEW kid that everyone wanted to try when the manual was published and no body knew that it could plug the barrel with a glob of partially melted powder.

Well;
sometime HS-6 and SR4756 will work in 9x19 loads......
I had a little trouble with these two in my 5" pistol finding "Good" accuracy but they did fair in my little 3.5".

Have fun.

Midway has Hogdon TiteGroup for $20/pound. As of 11/27/2020, 9:04PM CST.

Titegroup has a reputation for being good for 9mm.

...website for 'all loads using 2400 powder'. There was a 10mm load listed, but no 9mm. I'll bet you could get it to work, but I doubt the results would be very satisfactory.
