3. Always wear eye and ear protection.

While it is by no means a common occurrence, it is possible for the case rim to rupture when a rimfire firearm is discharged. The author has had it happen several times, and when it does hot gases as well as bits of powder and brass are ejected around the bolt face of the rifle (or out of the front or rear of the cylinder of a revolver) . These are sufficiently energetic to cause eye injuries. Even when the case rim does not rupture, the gap between the cylinder and barrel in a revolver can allow bits of unburned powder or lead shavings to escape. Modern rimfire ammunition is extremely good, but the author recently had four rounds of 22 LR target ammunition from the same box misfire. Moreover, two of these rounds misfired in each of two bolt action rifles. After waiting a short time with the muzzle remaining pointed at the target, the bolt was carefully opened and the round gently removed by pulling the bolt back. In such instances, it is possible for a “hang fire” round to detonate inside the open action causing all sorts of debris to be launched in all directions. If such an event happens, the shooter had better be wearing eye protection. Depending on the type of backstop being used, it is also possible that some small particles of the lead bullet may ricochet. Eyes are delicate and it is prudent to use every precaution possible to prevent eye injury. Participants in paintball sports are certainly aware of this requirement.
