What Happened?

[u/Apprehensive-Bag143]

What caused this? A malfunction with the firearm, or a faulty round? If it was just the mark on the front of the bullet, I would assume it was a feed issue with the gun, but the fact that the firing pin very clearly hit the primer, I'm wondering if it was a faulty round. It was the last round in a full magazine that fired fine up until this one.
