Which of the following is a safe method of pouring powder into a muzzleloader?

Using a pre-measured loader is a safe method for pouring powder into a muzzleloader because it ensures consistent and controlled amounts of powder are used each time. This method minimizes the risk of overloading the barrel, which can lead to dangerous situations such as misfires or barrel explosions. The pre-measured loader is designed specifically for this purpose, allowing the user to accurately measure the powder without the risk of spills or uncontrolled flow.

Additionally, this method isolates the powder from environmental factors that may lead to accidental ignition and provides a safer, more efficient means of loading. Other methods, such as pouring directly from the powder horn or using any available container, can introduce risks associated with over-pouring or contamination of the powder, which can compromise safety and performance. Although using a funnel can help direct the powder into the barrel, it may not provide the same level of control that a pre-measured loader does.
