This video details a ballistic gel test of the PMC Ultramag Tubular .38 Special +P ammunition, often referred to as 'cookie cutter' rounds. The test involves chronographing velocities from two different barrel lengths and firing rounds into gel with a clothing barrier. The results show the unique tumbling and limited expansion characteristics of this tubular projectile design, offering insights into its historical performance and potential effectiveness.

Quick Summary

The PMC Ultramag Tubular .38 Special +P ammunition, also known as 'cookie cutter' ammo, features a 66-grain tubular copper projectile. Tested in ballistic gel, it averaged 1432 fps from a 2" barrel and 1592 fps from a 4" barrel, tumbling upon impact with approximately 11.5 inches of penetration and no expansion.

Frequently Asked Questions

What is the PMC Ultramag Tubular .38 Special +P ammunition?

The PMC Ultramag Tubular .38 Special +P is a unique ammunition type featuring a 66-grain tubular copper projectile with an axial hole. It was historically known as 'cookie cutter' ammo and is tested here for its ballistic performance.

What were the chronograph results for the PMC Ultramag Tubular .38 Special +P?

From a 2-inch barrel, the average velocity was 1432 feet per second. From a 4-inch barrel, the average velocity increased to 1592 feet per second, showing a significant gain with the longer barrel.

How did the PMC Ultramag Tubular .38 Special +P perform in ballistic gel?

In ballistic gel tests with a clothing barrier, the projectile demonstrated a tendency to tumble, causing disruption but no expansion. Penetration was approximately 11.5 inches, and the internal plug often separated upon impact.

Is the PMC Ultramag Tubular 'cookie cutter' ammo considered effective?

While it performs as designed by tumbling, the reviewer considers it a 'gimmick' due to its high cost, limited availability, and lack of expansion compared to modern ammunition. It's seen more as a collector's item or historical curiosity.
