The loading and firing of one of these cannon was a complicated procedure, requiring the assistance of several men. The recoil from the discharge would normally drive the piece back away from the gun port. If it did not roll back far enough, the crew would seize the ropes or “training tackle” and haul it into a position that would permit them to load it. First a wet sponge on the end of a long handle was run down the barrel to put out any sparks that might remain from the previous shot. Then came the powder which was handled in one of two ways. Sometimes the proper amount was fastened ready-to-use in a cloth bag or cartridge. At other times it was brought loose to the cannon in a wooden bucket with a purse-like leather top closed by a drawstring. From this “budge barrel,” as it was called, the powder was dipped and inserted into the barrel by means of a copper ladle on a long wooden handle. After the powder was rammed home, a wad, was inserted and rammed, and finally the projectile which was forced home by a rammer.
This projectile might be either a solid ball or one of the more deadly anti-personnel missiles such as grape shot or cannister. Grape shot was made up of a series of small balls grouped on a wooden stand and wrapped with burlap or canvas. Upon firing, the stand and cloth disintegrated, and the balls spread out over a wide area. Cannister shot was based on the same principle. In this form, however, the small balls or other iron fragments were enclosed in a thin metal cylinder which came apart upon firing. Other missiles included cross bar and chain shot, in which spheres or hemi-spheres were joined by a bar or several links of chain. These were particularly useful against ships because they revolved in flight and cut rigging. It is doubtful if the Pilgrims had all of these forms of projectiles with them in 1620. Some of them were just then developing. But by 1690, any or all of them might well have been used at Plymouth.

Once the gun was loaded, a few more steps were necessary before it could be fired. It was primed by pouring powder from a flask or horn into the touch hole. Then the crew again seized the training tackle and pulled the gun back into position. The gunner aimed it by directing the way in which the men pulled the ropes and by shifting the position of the wedges under the breech of the barrel. Then he took a forked staff, known as a linstock, which held a length of burning match similar to that used in the matchlock muskets. He touched the lighted end of the match to the powder in the touch hole and fired his gun.
