The intent of the buck and ball load was to combine the devastating impact of a .50 to .75 caliber ball with the spreading pattern of a
shotgun. The combination served to greatly improve the hit probability of the smoothbore musket. In combat, especially at closer ranges, the buckshot would retain significant energy. When used against closely packed troops, the spread of the buckshot would be advantageous.
Claud E. Fuller, in his book
The Rifled Musket, shows tests of a rifled musket firing
Minié ball, and a smoothbore musket firing round ball and buck rounds at various ranges against a target. The firers consisted of several men in line shooting in volley. At ranges of and under, the buck and ball from the smoothbore musket, while less accurate than the rifled musket, produces a greater number of hits due to the greater number of projectiles. At , 50 shots by smoothbore buck and ball against the target result in 79 buckshot hits and 37 ball strikes, as opposed to 48 Minié ball hits in 50 shots. At , 37 of 50 Minié bullets struck the target, vs. 18 of 50 smoothbore balls and 31 of 50 buckshot, for a total of 49 hits in 50 shots. Beyond this range, the buckshot will have lost too much energy to be effective due to its lower
ballistic coefficient. == Use ==
