In response to the OP, yes. The projectile is pushed down the barrel by the esaping gases caused by the explosion (fast burn) of the propellant. If the propellant gas has no egress, ie., out the end of the barrel, the gases must go somewhere, which results in a shattered barrel end and/or shattered breech (where the catridge is loaded). This is more commonly seen with shotguns, as their barrel thickness is usually much less than a rifle, depending on it's configuration.
