"Another problem that can happen is if a lighter rebound spring is installed in a roughly finished frame this COULD prevent the positive return of the rebound spring body, and this would cause the cylinder to not line up with the forceing cone on fast double action shots.Tell me that would not BLOW apart a revolver."
If the rebound slide doesn't reset, that means that the trigger has not reset (the rebound slide/spring forces the trigger forward), and that obviously means that the hammer is down as the trigger seat/sear are out of engagement.
If the trigger doesn't reset fully, there's no way that it can pick up the hammer and fire the subsequent cartridge.
There's also the fact that while yes, it is possible for a round to be fired with the cylinder out of alignment, there's no way for a cartridge to be fired with it so badly out of alignment that the bullet will miss the bore completely.
IIRC small pistol primers (if we're still talking about the J frame, that's the only primer we're talking about) are 0.135 in diameter. (Humm... That dimension may be off. I need to check.)
Divide that by 2 (the firing pin strikes the center of the primer) and you get .0675 as an absolute maximum by which the chamber can be out of alignment with the barrle.
Given that the forcing cone is, in fact, cone shaped, that .0675 is effectively reduced somewhat, meaning that the vast majority of the bullet will still be aligned with the barrel, just not optimally.
The result in that case will be a badly shaved bullet, chunks of lead flying out the cylinder gap, and extremely poor accuracy, but the chances of it actually causing the gun to explode are virtually nonexistent.
