What are the advantages and disadvantages of the type of musket that the soldiers of Napoleon's Army used?

The Model 1766 Charleville musket in .69 caliber had a long and illustrious service history among blackpowder flintlock weapons. It was reliable, simple and effective. It had numerous improvements over earlier models of the same family group from its creation in 1717 and remained in active service until 1840. It was a half pound lighter then the Brown Bess which was made in .75 caliber but it still had plenty of punch at a range of 200 yards. It was sturdier then the Brown Bess for use as a club when required.
