What could potentially cause a shotgun to explode?

Using the wrong shotshell in your shotgun can lead to severe safety hazards, including the risk of an explosion. Each shotgun is designed to handle specific types and sizes of ammunition, which are matched to its gauge and chamber specifications. If a shotshell that is too powerful or too large for the chamber is loaded, it can create excessive pressure when fired. This overpressure may result in the barrel bursting, causing potentially serious injury to the shooter and those nearby.

In contrast, a barrel obstruction is another significant danger that can cause similar issues, as a lodged object can prevent the shot from exiting the barrel, leading to an explosion. Firing without eye protection, while unsafe for the shooter's eyes, doesn't directly contribute to the gun's mechanical failure. Lastly, cleaning the firearm immediately after use, if done properly, poses minimal risk compared to ammunition selection and is, in fact, encouraged to maintain a firearm's safety and performance. Understanding the importance of using the correct ammunition is essential for safe shotgun operation.
