That shouldn't happen to a Carcano. They're generally well made guns and have pretty good steel in them. Their design does however make them kind of clunky to use. They're not the smoothest guns, and the enbloc clips can be a PITA to deal with.
There were some that were modified (drilled) overseas so that they would be "inoperable" though. Often, this was done in a way that you could not see without disassembling the gun, and it would still be possible to load and fire a round. It's possible one of those made it into a batch that was imported. It's also possible that the ammo manufacturer screwed up and sent out a round that would make bubba's pissin hot reloads look mild. The shooter just won the bad luck and good luck lotteries simultaneously.
If you shoot/collect old guns, check them out BEFORE firing.
