The barrel fails as result of the force of the second round colliding with the first bullet not from pressure resulting from fire normal round (internal ballistics). These are technically refereed to as obstructions.
Cylinder failures are always the result of over pressure, barrel ruptures are typically the result of obstructions.
Peak pressure in 38 special (and most other strait wall handgun cartridges) occur before the bullet even leaves the cartridge.
Even when slower powders such as 4227 is used in even the largest of handgun cartridges such as the 460 S&W or 500 S&W and operate at twice the pressure of 357, the bullets still have not left the brass before the peak pressure has been reached.
