What should be done to prevent increased pressure in a firearm barrel?

To prevent increased pressure in a firearm barrel, consistently cleaning the barrel and avoiding excess lubrication is crucial. A clean barrel ensures that there is no buildup of fouling or debris that could obstruct the bullet's path, which can significantly increase pressure. An obstructed barrel can lead to dangerous circumstances, such as a barrel explosion.

Additionally, the right amount of lubrication helps to maintain the firearm's function without creating excess friction that can occur with too much lubricant or inadequate cleaning. This practice helps ensure that gas pressure generated by burning gunpowder within the barrel is properly managed, allowing for safe firing conditions.

While regular inspections for scratches are important for the overall maintenance and safety of the firearm, they do not directly relate to preventing pressure buildup. Firing lightweight bullets may also not necessarily prevent increased pressure, as it depends on the specific load and firearm specifications. Storing the firearm in a cool, dry place is essential for overall care and avoiding corrosion but does not have a direct impact on barrel pressure during firing.
