What makes smooth bore cannons accurate, but the same can’t be said for rifles?

1.19K views

Learning about modern main battle tanks, some of them have 120mm main guns that have a smooth bore muzzle as opposed to rifling. Historically, muskets and other muzzle loaded rifles weren’t considered accurate at anything resembling long or even moderate range. Rifling of the barrels dramatically increased accuracy. Have main battle tanks ever used rifled bores, and if not, how can the smooth bores be accurate enough to effectively engage targets at ranges over 3,000m?

The precision of those smoothbore cannons is _significantly_ better than any musket. They’re also computer-controlled to compensate the vehicle movement (be it ocean wavesor land inconsistencies) and aim.

Some tanks use sabot rounds, too, which interact differently with rifled barrels.
