What does the term "priming tool" refer to in muzzleloading?

The term "priming tool" specifically refers to a tool designed to assist in seating the primer into the firearm. In muzzleloading firearms, the primer is a critical component that ignites the black powder when a shot is fired. The priming tool ensures that the primer is securely and correctly placed in the firing mechanism, facilitating reliable ignition during shooting. Using a priming tool can enhance the consistency and safety of the loading process, making it an essential part of the muzzleloading setup.

In contrast, the other options are associated with different functions in the muzzleloading process. Cleaning tools are used for maintaining the barrel, measuring devices are involved in determining the correct amount of powder for a load, and aiming devices assist in improving accuracy when taking a shot. None of these functions pertain directly to the role of a priming tool, which is specifically focused on handling the primer.
