What was one advantage of using cartridges over the earlier methods of loading open gunpowder?

Using cartridges provides the significant advantage of being easily loaded compared to the earlier methods of using open gunpowder. In the past, loading a firearm required the shooter to measure out the correct amount of gunpowder, often leading to inconsistencies and potential safety issues with over or under-loading. With cartridges, everything is pre-measured and contained within a single unit, which makes the loading process much quicker and more efficient. This convenience allows shooters to spend less time preparing their firearms and more time focusing on their use.

Other aspects, such as complexities in mechanisms or higher costs, do not support the notion of cartridges being advantageous over the laborious and error-prone process of loading loose gunpowder. The focus on ease of use highlights the practical improvements brought about by the introduction of cartridges in firearm technology.
