Do cannons need gunpowder?

Some cannon made during this time had barrels exceeding 10 ft (3.0 m) in length, and could weigh up to 20,000 pounds (9,100 kg). Consequently, large amounts of gunpowder were needed, to allow them to fire stone balls several hundred yards.

How much gunpowder does a cannon use?

The United States manual of 1861 specified 6 to 8 pounds for a 24-pounder siege gun, depending on the range; a Columbiad firing 172-pound shot used only 20 pounds of powder. At Fort Sumter, Gillmore's rifles firing 80-pound shells used 10 pounds of powder.
