A shotgun explosion is an extraordinarily rare event, but there are several potential causes that shooters should be aware of and take steps to avoid if they wish to prevent serious injury or death.
The first and most obvious cause of shotgun explosions is overloading the shotgun with too many shotshells. All shotguns are designed with a maximum number of shells they can safely fire at once; exceeding this maximum risk catastrophic gun failure, as the added pressure is too great for the shotgun to contain. For this reason, shooters should always pay attention to their gun’s designated shell capacity and remain compliant with that number.
A less common, but still quite serious, cause of shotgun explosions is blockage in the barrel. When a shooter fails to properly clean the shotgun’s barrel, the accumulation of burnt residue and plastic build-up can dangerously impede the exit of the bullet. These blockages essentially act as a plug, trapping the escaping pressure and causing the gun to explode. This condition can also be caused by a shooter mistakenly firing a slugshell instead of a shotshell. Slugshells usually have a larger diameter and can easily jam in a shotgun’s barrel if a shotshell chamber isn’t used. To reduce the risks of such incidents, shooters should always be mindful of the type of shell they are loading and regularly clean the barrels of their firearms.
The age of a shotgun can also contribute to an explosion. Over time, a gun’s seals and rivets can become weak and worn due to their repeated exposure to pressure and extreme temperatures. Worn seals and rivets can cause an avalanche of different malfunctions and lead to premature detonation. As such, regular maintenance and periodic inspections of a gun’s components are essential for the prevention of explosions.
Lastly, the quality of the ammunition used is a key factor in preventing shotguns from exploding. Unreliable and poorly manufactured ammunition may have defects that greatly elevate the pressure within a barrel, often resulting in explosion. To lessen the odds of buying defective ammo, shooters should do their research and buy from reliable retailers. Additionally, they also should inspect all shells they purchase for visible defects, such as cracked wads or loose shot pellets, before using them.
Overall, a shotgun explosion is an incredibly rare event and is usually caused by a shooter’s negligence. To minimize the chances of such a mishap, shooters should practice safe gun handling, properly maintain their firearms and make sure to inspect any ammunition before using it. Doing so can help to ensure that hunters and other shotgun users are operating their weapons safely and responsibly.
