It'll work fine for blasting ammo...that's basically what it's for, but for all the variables that come into play with surplus powders...with a few exceptions...if it is priced anywhere near commercial powders, buy it cheap or I would just get 8# of a fresh commercial powder.
There was some reason(s) why it was surplused. It might be too old, too much flash...burn dirty...not temp resistant.
8# of fresh commercial powder will also load 2k of 223 ammo at about .05 a round.
