Which issue indicates that the bullet does not feed from the magazine?

The issue that indicates a bullet does not feed from the magazine is referred to as a failure to feed. This problem occurs when the cartridge does not properly enter the chamber from the magazine, preventing the firearm from being ready to fire. It can arise from various reasons, such as a malfunctioning magazine, improper loading of ammunition, or even issues with the firearm's feed ramp.

Failure to extract occurs after a round has been fired, when the empty casing is not removed from the chamber. Failure to eject involves the spent casing not being expelled from the firearm, also occurring after firing. Failure to fire refers to a situation where the trigger is pulled but the gun does not discharge, which can stem from issues like a dead primer or mechanical failure within the firing mechanism. Each of these issues pertains to different stages of firearm operation, whereas failure to feed specifically addresses the problem of getting the first round into position, indicating a problem with the magazine or feeding system.
