Bloody Hell! I've, unknowingly, fired a second round which pushed a stuck round out, but only in 22 rimfire. It left and "O-ring" groove in the rifling and a swell in the barrel.
I wouldn't want to do it with a centrefire rifle, you'll blow your face off!
I have had one centre-fire projectile which came out of the case and jammed in the breech/rifling when I extracted the cartridge without firing. Obviously not seated correctly. The powder pouring into the magazine alerted me to the problem. Fortunately I always carry a cleaning rod in the ute and a very gentle tap dislodged the projectile without drama.
