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.
