This short demonstrates a 'keyholing' issue where bullets impact a target sideways, indicating tumbling. The speaker uses an Aero Precision 10.5-inch AR-15 with AAC 5.56 NATO 55 Grain FMJ ammunition and seeks audience advice to resolve the problem, as the rifle cycles normally.

Quick Summary

Keyholing occurs when bullets tumble and impact a target sideways, creating elongated holes. This can be caused by an incorrect rifling twist rate for the bullet weight, barrel damage, or inconsistent ammunition, preventing proper stabilization.

Frequently Asked Questions

What does it mean when bullets hit a target sideways or 'keyhole'?

Keyholing occurs when bullets tumble through the air instead of maintaining a stable flight path. This results in elongated, oval-shaped holes on the target, indicating the bullet is impacting sideways rather than nose-first.

What are common causes for bullet keyholing in an AR-15?

Common causes include an incorrect rifling twist rate for the bullet weight (too slow), a damaged barrel, or inconsistent ammunition. The bullet may not be stabilizing properly during flight.

What ammunition was used when the keyholing occurred?

The ammunition used in this demonstration was AAC (America's Ammunition Company) 5.56 NATO 55 Grain Full Metal Jacket (FMJ).

What firearm was used and what were its specifications?

The firearm was an Aero Precision 10.5-inch AR-15. It was equipped with a Streamlight ProTac weapon light and a Holosun red dot optic. The barrel had approximately 500 rounds through it.
