What aspect of muzzleloader maintenance is crucial for durability?

Regular cleaning and oiling are essential for maintaining a muzzleloader's durability because these practices help prevent corrosion and buildup of residue that can lead to malfunction. Muzzleloaders are particularly susceptible to rust due to their design and the materials used, which can be adversely affected by moisture and fouling from gunpowder and lead. Cleaning removes these residues, while oiling creates a protective barrier against moisture, significantly extending the lifespan and reliability of the firearm. Keeping the firearm in good working order ensures that it operates safely and effectively when you need it. Regular maintenance should be an ongoing commitment rather than infrequent or limited to specific seasons.
