NO. However, they can produce a VERY dangerous situation. The 20 gauge shell is small enough to slip into the BARREL of a 12 g, blocking the barrel. When a 12 g shell is fired, it will damage the gun, with a strong likelihood of injuring the shooter, and anyone nearby. This was the reason that most makers of shotshells began making 20 g shells with YELLOW cases, to prevent their being mistaken for 12 or 16 g shells.
