About Rifled Muskets :
Rifled Muskets use the same firing principles as flintlock muskets. The difference in this rifle is the barrel. On the inside of the barrel of this rifle there are rotating grooves worked into the metal. This improves aim and accuracy. Although the principle of rifling started in the early 1700s, it was not common until the end of the 1800s, when different ammunition improved the longevity of the barrel. Until that point, the rifle could not be loaded after a few rounds had been fired, due to warping of the barrel.
