Knox Ballistics Gelatin Initial Test Results

Published on April 2, 2012
Duration: 3:35

This video details preliminary testing of homemade ballistics gelatin using standard Nox gelatin. The goal was to simulate FBI calibration standards for testing defensive ammunition. While the homemade mix proved to be a viable, cost-effective alternative for preliminary testing, it did not meet the FBI's strict penetration requirements for calibration, suggesting a need for higher bloom gelatin for more precise testing.

Quick Summary

Homemade ballistics gelatin can be made using standard Nox gelatin, typically at a ratio of two packages per cup of water. While cost-effective for preliminary testing, it may not meet strict FBI calibration standards, which require 8.3-9.5 cm penetration from a 17-caliber BB at 600 fps. For precise testing, 250 Bloom gelatin is recommended.

Frequently Asked Questions

How can I make homemade ballistics gelatin for testing?

You can make homemade ballistics gelatin using standard Nox gelatin, typically at a ratio of about two packages per cup of water. This mix is then heated and poured into a mold. For a quart of material, this would equate to roughly eight packages of Nox gelatin.

What are the FBI's calibration standards for ballistics gelatin?

The FBI calibration standard for ballistics gelatin involves firing a 17-caliber BB at 600 feet per second into the gel. The gel is considered calibrated if the BB penetrates between 8.3 and 9.5 centimeters.

Does homemade Nox gelatin meet FBI calibration standards?

In preliminary tests, homemade Nox gelatin did not consistently meet FBI calibration standards. A BB fired at the correct velocity passed straight through a 17 cm block, indicating penetration beyond the required range, suggesting a need for higher bloom gelatin.

What is the purpose of ballistics gelatin testing?

Ballistics gelatin is used to simulate the behavior of soft tissue when penetrated by a projectile. It helps in understanding how ammunition performs, including penetration depth, expansion, and energy transfer, which is crucial for evaluating defensive rounds.
