The importance then of allotting to all ships the largest cannon they can with safety bear being granted, it remains to show on what foundation a change is proposed to be made in the fabric of all pieces from eighteen pounders downwards, so that they may be changed for others of the same, or less weight, but of a larger bore.

The 24-pound guns each required a gun team of 6-14 men to operate and weighed about 5600 pounds. They are called 24-pounders because they fired a cannonball that weighed 24 pounds. Although the solid 24 pound shot is what was commonly used, the guns could be loaded with a combination of projectiles. The long gun possessed one great advantage: it could far outrange the carronade, and if well operated had a chance of crippling the enemy before coming to close quarters.
The normal gunpowder charge used for these guns was six pounds and their maximum range was about one mile at maximum elevation, but due to inaccuracy at that range this was literally a "long shot." The maximum effective range of a 24-pounder was about 1200 yards. The usual engagement range, however, was much closer. CONSTITUTION engaged HMS Guerriere in 1812 at about 25 to 50 yards. At this range CONSTITUTION's guns could do terrible damage, with her cannonballs penetrating over two feet of oak planking.
The 32-pounder Navy gun [length 112 inches, 57 hundredweight] was intended service was on first class frigates and ships of the line. A total of 744 smoothbore guns of this type were manufactured at five different foundries from 1846 to 1852.
