Intruder In a Box

Intruder In a Box Unbounded Ballistic Solutions is a research and design company owned by biomechanist and engineers

The Intruder in a Box replicates the anatomical variation in material properties of the intended target. Panels of material simulating skin, muscle, bone, and internal organs are layered in the appropriate order to create a realistic platform for ammunition testing. Multiple sections (9 shot model) are arranged in each box for comparing different loads. Ballistic Boxes will be available for differ

ent species of game, as well as the Intruder in a Box, developed to test personal defense ammunition. Unlike ballistics gelatin, the Intruder in a Box is easy to use. Nothing needs to be mixed, calibrated, or stored at specific temperatures. The Intruder in a Box also takes into account the changes in pe*******on and wound cavity when a projectile interacts with different anatomically accurate simulants.

“Being a shooter and hunter for over 30 years, I’ve always been interested in terminal ballistics. With my experience as a biomechanist, I knew there had to be a better way to test ammunition than using homogeneous materials like ballistics gelatin. Our team developed a platform that would allow shooters to test their specific load on an anatomically correct target that gets enough shots in to draw a valid conclusion about how effective their ammo is.”

In 1988, the FBI produced the first protocol for testing ammunition. Intruder in a Box has updated this testing protocol to modern standards.

Even we are frequently surprised.

Had a routine range trip today and wanted to try some new stuff.

On the top 2 rows, can you tell which load made it all the way through? Same bullet, 2 different calibers .45 nd 9mm).

Top row was 2 shots of a +p+ mid weight 9mm load in a subcompact pistol. The middle was 3 shots of 230 grain .45

Top left was a different 9mm we tested for a new batch of ammo against known data.

Subsonic 9mm on the bottom did fine in a carbine. 2 shots embedded in the bone and muscle sheet on the back and one just barely made it through the bone with minimal muscle damage.

As usual, they never look as pretty as they do in ballistics gel.
