Before you load your firearm, open the action and be certain that no ammunition is in the chamber or magazine. Be sure the barrel is clear of any obstruction. Even a small bit of mud, snow, excess lubricating oil or grease in the bore can cause dangerously increased pressures, causing the barrel to bulge or even burst on firing, which can cause injury to the shooter and bystanders. Make it a habit to clean the bore and check for obstructions with a cleaning rod immediately before you shoot it. If the noise or recoil on firing seems weak or doesn’t seem quite “right,” cease firing immediately and be sure to check that no obstruction or projectile has become lodged in the barrel.
Placing a smaller gauge or caliber cartridge into a gun (such as a 20-gauge shell in a 12-gauge shotgun) can result in the smaller cartridge falling into the barrel and acting as a bore obstruction when a cartridge of proper size is fired. This can cause a burst barrel or worse. This is really a case where “haste makes waste.” You can easily avoid this type of accident by paying close attention to each cartridge you insert into your firearm.
