Bullet setback is when the bullet is pushed back further into the casing than it would be normally. This is generally caused by constantly chambering the same round, and happens most often in semi-automatic pistols. Cannelures help to prevent this from happening.

This can cause unsafe spikes in pressure. Cartridges that are affected by this issue should not be fired.
