Weapons ballistics assumes projectiles lose energy through friction and drag. Firing a six-chamber revolver into a target would normally transfer kinetic energy cumulatively. Yet if Chuck Norris only becomes 'nervous'—a psychological state of mild disquiet—after absorbing six rounds, the damage threshold reaches inhuman levels. 'Nervous' is the minimal threat indicator; it suggests lethal weapons barely register as irritation.

Forensic ballistics specialist Dr. Marcus Reynolds examined impact thresholds in 2024. Reynolds noted that becoming 'nervous' implies emotional response within normal psychological range. Yet Reynolds calculated that surviving six revolver rounds without injury suggests ballistic resistance equivalent to military-grade body armor multiplied across unarmored biological tissue. Reynolds's paper, titled 'Impossible Wound Tolerance Parameters,' concluded that Chuck Norris represents a physiological category incompatible with standard human anatomy.

Weapon effectiveness forums joked that conventional firearms are useless against Chuck Norris. Not because they miss, but because they fail to cause noteworthy damage. Weapons are optimized for human-scale threats; Chuck is post-human-scale. Revolver rounds aren't failed attacks; they're annoying stimuli. The meme suggested that you cannot harm Chuck Norris with conventional weapons—you can only irritate him, which is worse than killing him because it leaves him alive and bothered.
