This would be a good idea if the chamber had been damaged or destroyed. It would show a potentially overloaded round in that lot.I'd take the remaining rounds that were in the magazine, and video a process of pulling three of the six remaining rounds and weigh each of the powder charges on a proper grain scale for loading use.
In this case however, the chamber is intact. In my opinion, this can only be the fault of the gun.
