This is from the 1991 Hercules Reloaders Guide....

Caliber: .223 Rem
Bullet: Hornady 55 gr FMJBT
Primer: Fed 205
Powder: Hercules (Alliant) 2400
Chg Wt: 14 gr.
FPS: 2,685

Has anyone ever tried this? It certainly would make for inexpensive plinking loads. The fast burning powder may be an advantage in all those short- barreled ARs out there. Your thoughts?

Fast pistol powders can be a problem in an AR or other semi-auto. Not enough port pressure to completely and safely cycle the action.

I would be cautious using Hercules data from 1991 to load Alliant 2400.

I have heard from more than one reliable person that 2400 has become a faster burning powder over the years.

Good luck.

I agree with the above...I want accurate loads that cycle my AR's action every time.

Not worth the BS, just to save a few grains per round.

DO NOT USE THE OLD DATA!!!

I did for some .357 mag. loads. It's a good thing I was shooting a Blackhawk. The burn rate of the powder has changed since the Hercules days. Don't use Hercules data for A 2400 loads.
This is just advice. You may and will do what ever the he^^ you please.

As other have said don't use old date,powder companies are always changing there min. and max data with a given calibers ,Alliant says there is no difference between the old and new 2400 formula. Some extensive testing by Larry Gibson on the cast bullets forum with several canister of the old Hercules and several new canisters of the new 2400 in several calibers with identical loads showed only a 2% difference in MV and pressure between the two which is about the normal lot to lot variation.


2400 is and excellent powder in several semi-auto rifle calibers 30 carbine,SKS & Ak rifles. 12.5 grs of Allaint 2400 cycles my Chinese SKS all day long with 165 gr. bullet MV is around 1500 fps. drops the brass right at my feet,the Max. load 15.0 grs. runs about 2000 + fps. on the chrono. My advice would be to call Alliant and Hodgdon. I know Hodgdon has a couple powders for low velocity plinking loads such as Titegroup and Trailboss but I don't know if they will cycle the action of the AR.
