2400 powder

2400 was the king of 357Mag powders for several decades. It has a small particle size and meters well. It's still on the "Top 10" list, but has been toppled from its perch by more modern powders.

It's an excellent powder for magnum revlover. similar in bruen rate to H110/win296, but doesn't require a magnum primer.

One of the very best middle of the road Magnum handgun powders, modern derivation of the old Hercules 80 powder. This powder was THE powder used in development of the .357 Magnum and Elmer Keith used in the .44 Magnum. Can be used in heavy .38 Special +P loads.

Relatively insensitive to many issues other than detonation caused by low powder charges. Very consistent velocities.

Wide application of uses such as .30 Carbine and .410 shotshells.

Not quite as slow as H110, closer to Accurate #9, but can be loaded down without problems. Shooters tend to be a conservative bunch and its been around a long time, so many adherents. It no longer gives top, top velocities, but is more versatile, and there is tons of data out there for it.

I tried a can many years ago in the .41MAG and .45 Colt, I wasn't that impressed with it. Where it really shines is pistol cartridge rifles, where the slower burn rate takes advantage of a longer barrel. It's also a good powder for reduced rifle loads... I've used it in reduced .45-70 loads where it provides good velocity and reasonable case fill (for a reduced charge.) Other substitutes would be IMR4227 (which is what I use...) H4227, and AA#9. The flat out velocity winner in pistols is H110/W296, however.

H110 is a better top performing powder but really shines when pushed to near maximum charges. It will burn cleaner, more consistent ignition, and lower Std Dev velocities when pushed harder.

2400 or Unique is the old gold standard for reduced milsurp rifle gallery loads. .32 ACP cast bullets in Mosins or Enfields for instance. H4895 really shines for reduced rifle loads.

I use it because I can knock out 357 41 44 and 45LC all with one powder

Its also a bit more comfortable or relaxed relative to charge volume & charge weight vs case volume.

It does what it does very well. It works week in 357Mag, 41 Mag, 44 Mag and 45 Colt for full power loads. Its still readily available. ( well, before the pandemic)

2400 was Elmer Keith's ''go to'' powder when he developed the 44 Magnum cartridge. It is still used for those old timers who still shoot the 22 Hornet...I still do.

I would be lost without 2400, in my M1 Carbines, and my 44 mag loads. Thank God, after the Obama reduction of product, I stocked up on it heavily, and don't have to worry about running low for a very long time. It is the number one powder, for shooting 44 mag, out of my Desert Eagle, Magnum Research BFR, and my Super Redhawk.

In my book, there are three magnum handgun powders. I realize there are more, but 2400, IMR 4227, and H110 do everything I ask of my cartridges (and more).

Excellent for 357 Mag (-), 44 mag(-) hot 45 Colt. Sometimes H110 or lil gun is just too much.

Excellent in cast 308, 7.62x54, 30-30 loads. Excellent in reduced jacketed loads in the same bottleneck calibers.

I panic when I start to run out and buy it most every time I see it.

Dunno about the manufacturing of 2400, but I still have about 2 1/2-3 lbs left. It is my go to 44 Magnum, big boomer powder. I used a lot in my magnum handguns and pistol cartridge carbines. Old school? Maybe but it works quite well (I even used some in my cast .223 loads). For my use it is a bit more versatile than H110/W296...

You forgot Blue Dot
I like 4227, H110, and Blue Dot.
I do have several pounds of 2400 I bought for testing cast rifle. So far it's not out shining 4227.
I know I'll find something it's great in.

I like 2400 for big boomer .44 mag loads.

Its one of the powders slow to make a return here. I wish I had some.

14 grains in a sweede is a wonderful cast load. Little dirty but there is always a cost.

Hi...
I use 2400 for full power loads in .44Mag, .41Mag and .45Colt. I like that it has a larger operating window than H110/W296 and gives high velocity and accuracy across multiple revolvers and lever guns. I use Unique for general purpose loads in those cartridges
I use Blue Dot in .357Mag general purpose loads and H110/296 for full power loads.

I didn’t know it was a standard powder for 357 Magnum. I bought some for cast loads in my 30-30. It’s listed for cast loads in my Lyman Cast Bullet Handbook pretty regularly. I haven’t loaded any yet but it’s next after I finish with these 150 grain soft point round noses.

I prefer it to H110 because it is faster. I can squeeze another 100 fps out of my four inch barrel with 158 grain XTPs.

It's great in .357 with 158s of any flavor, and works in 300 BLK as well.

I agree, goes good with MBCs 158 gr SWC.
In 300 BLK, subs or super?

It works well for light/moderate loads in 45-70 with 405gr cast bullets, but so do a dozen other powders.
OK in 357, 41 and 44 mag revolvers but I much prefer H110 for heavy loads.
