Which was exactly your failure with the revolver?
The only ammunition-related cause I know that could turn a revolver unable to shoot is a bullet stuck in the barrel or forcing cone, and this because of a squib load. Judging for your comment on the cylinder locking I suspect you are talking about a bullet stuck at the forcing cone. It's real, in this case you have just a club in your hand. But exactly the same applies in case a bullet get stuck inside of a semiauto barrel, so such problem let both guns at the same level of un-usefulness.
And in case you may experience something like this in a semiauto you cannot clear it by hand neither.
Yep. I’ve had that malfunction in both, and it turned both into clubs. It’s not just a revolver thing.
