For a typical rifle or handgun bullet fired straight up, it usually takes on the order of 40–90 seconds to go up and come back down, depending on caliber, angle, and muzzle velocity. That spread is large because the exact time depends heavily on how fast it leaves the barrel and how close to perfectly vertical it is fired.

Basic idea

  • When a bullet is fired upward, it slows down due to gravity and air drag until it briefly stops at its highest point, then falls back down.
  • If fired near straight up with common rifle speeds, the total “up and down” time can be roughly 1–1.5 minutes in idealized calculations, but real-world times cluster more in the 20–90 second range once air resistance and non‑perfect angles are included.

Why the time varies

  • Muzzle velocity: Faster bullets take longer to slow to a stop on the way up, so they reach higher altitudes and stay in the air longer.
  • Firing angle: Even a small tilt away from vertical makes the path more of a long arc than a straight up‑and‑down flight, often shortening the time overhead at one spot.
  • Shape and mass: Different bullet shapes and weights interact with air differently, changing how quickly they lose speed and what terminal velocity they reach on the way down.

Danger from falling bullets

  • As a falling object, a bullet eventually reaches a terminal velocity where air resistance balances gravity, which can be on the order of a few hundred feet per second for typical bullets.
  • Studies and real incidents show that these speeds can still be lethal , especially if a bullet happens to strike someone in the head or upper body.

Key safety takeaway

  • Firing guns into the air is dangerous because the shooter cannot control where the bullet will land and because the falling bullet can still cause serious injury or death.
  • Many jurisdictions treat celebratory or random aerial gunfire as a serious criminal offense due to the documented risk to bystanders.
