This video demonstrates the distinct sounds of supersonic rifle fire from 400 yards, differentiating between the sonic crack of projectiles passing and their impact. It uses an AR-15 and AK-47 to illustrate how sound travels and the audible effects at varying distances off target, providing a practical understanding of long-range ballistics. The content is presented by CajunBoyJake, a firearms enthusiast.

Quick Summary

From 400 yards, supersonic rifle fire from an AR-15 or AK-47 produces a distinct 'crack' as rounds pass, followed by a delayed impact sound. This sonic crack diminishes in intensity but remains audible at distances like 50 and 100 yards off target, illustrating the sound propagation and danger zone.

Frequently Asked Questions

What is the primary sound difference when being shot at from 400 yards?

From 400 yards, you'll primarily hear the distinct 'crack' of supersonic rounds passing by before the delayed 'thud' of impact. This sonic crack is a key indicator of incoming fire at long distances.

How does distance affect the sound of rifle fire from 400 yards?

As demonstrated, the sonic crack becomes less intense but remains audible at 50 and 100 yards off target. The report of the rifle itself is also delayed due to the distance the sound must travel.

What firearms were used to demonstrate the sound of being shot at?

The demonstration featured an AR-15 rifle, typically firing 5.56x45mm NATO / .223 Remington ammunition, and an AK-47 rifle, commonly chambered in 7.62x39mm ammunition.

What is the significance of the 'sonic crack' in long-range shooting?

The sonic crack is the audible shockwave created by a projectile traveling faster than the speed of sound. It's a critical auditory cue for identifying the direction and proximity of incoming supersonic rifle fire.
