Question: 1 / 400

Why is it considered dangerous to leave heavy grease or oil in the bore of a firearm?

It attracts dirt and debris

It can cause misfires

It can increase chamber pressure to dangerous levels when fired

Leaving heavy grease or oil in the bore of a firearm is particularly dangerous because it can increase chamber pressure to dangerous levels when the firearm is fired. When a bullet is fired, it generates a rapid expansion of gases. If there is an excessive amount of grease or oil in the bore, it can create a situation known as overpressure, where the resistance from the trapped lubricant can cause the pressure within the chamber to rise significantly beyond safe limits. This excessive pressure can lead to catastrophic firearm failures, potentially resulting in injuries to the shooter or bystanders, as well as damage to the firearm itself.

Understanding this risk highlights the importance of proper maintenance and cleaning of firearms, ensuring that the bore is free of excess lubricants before firing. This not only promotes safe operation but also enhances the reliability and performance of the firearm.
