    What powder does the military use in 5.56 ammo?

    Does anyone know what powder the military uses in its 5.56 ammo? I reload my own and have tried several kinds of powder and can only manage about 2800 fps out of my 16" long 1 in 8 twist barrel. I'm trying to get as close to 3000fps with a 60 Gr. Hornady bullet as i can and still be safe.
    The reason I'm asking this is I've shot some 55 Gr. military bullets over my chronograph and they travel at an average of 3030 fps. I've pulled a few bullets from them and it looks like Win. ball powder, possibly 748. I don't have the funds to do a lot of experimenting. Any input will be appreciated.
    Ty,

    I was under the impression that it's a proprietary powder of some sort. It also suppresses muzzle flash.

    You are loading to 5.56 NATO specs and not .223 spec, right?
    Don't mind me, I'm just making sure I'm on all of the watch lists.

    I always thought it was a ball powder?? I have some Winchester 5.56 with a 55 gr. bullet.

    accurate powder makes a double base, ball propellant designed for the 5.56 called 2230.

    This link should answer your question. Mfg are allowed to change powders if they can achieve specs required by the military and a different powder may substituted that is not on this table.

    Thank you all for the replies and thanks Bullseye Shooter for the link. Judging from the chart there My mil. rounds are loaded with wc844 as they contain 28 Gr. of powder. I typed wc844 in a search and found a couple of places i might find it if it's still available, although a thread posted on that search said the supply had dried up.
    On the same thread it was said that H335 had identical characteristics. I'll try H335 and if it doesn't work I'll put my trusty pliers to work pulling bullets and steal powder from some of my mil. rounds seeing i have a couple thousand rounds. BTW country boy AA2230 is the best powder I've tried so far. Hogdon Varget is a close second but it fills the case to capacity and i ruin my thin walled VMAX bullets with the seat die.
    Thanks again y'all. I'll let you know if i have any success.
