In reality, not much. The constituents of gunpowder (charcoal, sulfur, and saltpeter) are all consumable. It might loosen his bowels a bit though.
There is a southern tradition of feeding gunpowder to runts of the litter with the intention of toughening them up. Although how doing this accomplishes the intended purpose is not clear. It did seem to work, however, with my grandfather's last coonhound, Deacon. Deacon was born a week before me, and was the runt. Grandpa cracked a .22 bullet every time he fed Deacon and sprinkled the powder over his food; by the time Deac and I were a year old, I could ride him like a small horse. Grandpa was well over six feet tall, and when Deacon stood on his hind legs to give Grandpa "a kiss,' his front paws rested comfortably on the old man's shoulders.
