This video demonstrates the performance of a unique Argentinian HEI Spotter round, featuring an internal detonator, compared to a standard FMJ. Through a series of tests on various targets including rubber, steel, aluminum, lumber, water, ballistic gel, and real hog meat, the detonating bullet consistently showed significantly more destructive power upon impact. The tests highlight the effectiveness of this specialized ammunition for rapid target neutralization.

Quick Summary

A detonator bullet, such as the Argentinian HEI Spotter, contains an internal explosive compound activated by a firing pin mechanism upon impact and deceleration. This causes a detonation, resulting in significantly more destructive effects than standard FMJ rounds.

Frequently Asked Questions

What is a detonator bullet and how does it work?

A detonator bullet, like the Argentinian HEI Spotter tested, contains an explosive compound. It features an internal firing pin mechanism that activates upon impact and deceleration, causing the compound to detonate and create an explosive effect.

How does an Argentinian HEI Spotter round differ from a standard FMJ bullet?

Unlike a standard FMJ bullet which relies solely on kinetic energy transfer, the Argentinian HEI Spotter round is designed to detonate upon impact. This results in a significantly more destructive effect, characterized by explosions and larger wound channels.

What were the observed velocities of the Argentinian Special bullet?

During testing with a 21-inch barrel, the Argentinian Special bullet achieved consistent velocities, with a minimum recorded at 2522.0 FPS and an average and maximum of 2545.3 FPS.

What kind of damage did the detonating bullet cause to ballistic gel?

The detonating Argentinian Special round created an extremely violent and massive wound channel in ballistic gel immediately upon entry, far exceeding the damage caused by a standard FMJ bullet, which tumbled and expanded later.
