Shotgun shells can last for years, but their shelf life depends on the type of ammunition. The most popular shotgun shell is a 12 gauge, which comes in a variety of sizes.

Shotgun shells are made from a combination of metal and plastic. They have a primer that ignites when it’s struck by a firing pin. This causes the round to fire and send hundreds of pellets flying downrange at high speeds.

The average lifespan of shotgun shells is one to two years, with some lasting as long as three years. This depends on how often you shoot and whether or not you keep them in storage conditions that protect them from moisture, heat and extreme cold.

If you’re shooting regularly and storing your shotgun shells properly, they should last up to three years without any problems. If you don’t use your ammunition often or store it improperly, then there’s a chance they could become damaged before they expire.
