Did the Minie Ball have a noticable impact on military tactics?

by tuttifrutti1955

The Minie Ball was invented in 1849 and was used in the Civil War. Was there a difference in tactics that is noticeable when comparing say the Civil War to the War of 1812, or Mexican American War?

No. The Minie Ball's effect on Civil War combat is a continued source of debate, but modern scholars tend to lean more towards the position that its effects are vastly overstated in popular culture.

Rifled muskets are capable of exceptional accuracy, even at long ranges. A skilled marksman can engage targets with a rifled musket out to at least a mile, if he has optics to see, maybe even farther, and there are occasions during the war when snipers on both sides took advantage of this capability to eliminate enemy artillery crewmen, signaleers, and other important targets. However, rifled muskets have a low muzzle velocity. This means that while a Minie Ball's trajectory is fairly flat out to about 150 yards, it is very arced (sometimes called a "rainbow trajectory") at long ranges. The farther away, the steeper the trajectory. This steep trajectory requires exceptionally accurate range estimation to hit the target, to within about 10-20 yards. Such estimation is very difficult, further compounded by the stress and exhaustion of battle and smoke obscuring the enemy. And if the enemy is 500 yards away and marching towards you, then every one or two shots requires a range adjustment.

What all of this adds up to is that while rifled muskets are theoretically far more capable than smoothbores and could have forced significant changes in tactics, it wasn't practical for the average infantryman to leverage their technological advantages in the heat of battle. This is borne out by the engagement ranges: firefights in the American Civil War averaged 100-150 yards, compared to about 100 yards in the Napoleonic Wars.
