Frequently Asked Questions

What happens if you mix 12 and 20 gauge shotgun shells?

Mixing 12 and 20 gauge shells is extremely dangerous. A 20 gauge shell can fall into a 12 gauge barrel and lodge. Firing the 12 gauge shell afterward can cause the barrel to burst catastrophically, posing a severe risk to the shooter.

How can I prevent mixing shotgun gauges?

To prevent mixing gauges, always empty your shooting vest after use. Keep 12 gauge and 20 gauge ammunition strictly separated in your storage and during handling. Pay close attention when loading your firearm.

Why is a 20 gauge shell dangerous in a 12 gauge barrel?

A 20 gauge shell is smaller and can slide past the chamber of a 12 gauge shotgun, lodging in the barrel. When a 12 gauge shell is fired, the obstruction created by the lodged 20 gauge shell causes immense pressure, leading to a barrel rupture.

What visual cues help distinguish 12 and 20 gauge shells?

While not universal, 12 gauge shells are often red, and 20 gauge shells are frequently yellow. This color coding can serve as a quick visual reminder, but it's crucial not to rely solely on color. Always check markings and handle ammunition carefully.
