powder in the Mk 262 mod 0, 223

Any body know the powder that is used in this military round? The load is the Sierra 77gr bthp in 223.

TAC, available from Western Powders (Ramshot).
Adjust the dose so you are getting 2770 fps 10 feet in front of a 20" barrel. CCI #41 primers.
Lake City cases.

I also use pre-primed Remington cases.

I pulled some bullets and the powder was ball, looked like 748. Montana's website says their powders are sepherical. Any thoughts on that?
