SECOND ENCLOSURE
The purpose of this project is to determine, with as great a degree of precision as possible, the range of artillery used by His Majesty's Armed Forces, and the methods of accurately firing upon targets at various distances from the cannon.
After a great deal of research, the following factors have been found to affect the distance which a cannon ball may be hurled by exploding gunpowder:
1. Weight of the cannon ball.
2. Weight of powder used.
