Frequently Asked Questions

What makes the Argentinian HEI Spotter bullet unique?

The Argentinian HEI Spotter bullet features an internal detonator mechanism with a firing pin. Upon impact and deceleration, this pin strikes a compound, causing the bullet to detonate, which is designed to be effective even on softer targets.

How did the detonator bullet perform compared to a standard FMJ round?

In comparative tests, the detonator bullet consistently detonated upon impact, causing explosive effects, significant fragmentation, and massive wound channels. Standard FMJ rounds penetrated targets with minimal disruption and no detonation.

What were the key targets used in the ballistic testing?

The testing involved a variety of targets, including a rubber torso, mild steel plates, thicker aluminum plates, a lumber block, a water bottle, ballistic gel, and actual hog meat, to simulate different impact scenarios.

What velocity was recorded for the special detonator bullet?

The RangeCraft Chronograph measured the Argentinian HEI Spotter round fired from a 21-inch barrel with an average velocity of 2545.3 FPS, a minimum of 2522 FPS, and a maximum of 2545.3 FPS.
