It actually occurs IN the chamber. But unless there's some sort of obstruction directly in front of the chamber, or unless the chambers have been lengthened leaving insufficient wall thickness, that's a very unlikely place for a gun to burst.


Very few guns with lengthened chambers actually burst there. As stated very few burst in the chambers, the area of highest pressure. The reason is Very Very few guns actually burst from excess pressure. The vast majority of burst shotgun barrels are the result of an obstruction & next in line is flawed metal. Flawed metal it would seem is actually more prevalent in older methods of making steel barrels than it was with Twist & Damascus.
