.17 HM2 17 Mach 2 Ballistic Gel Test & Review

Published on December 30, 2024
Duration: 7:09

This video provides a ballistic gel test comparing CCI and Hornady .17 Mach 2 ammunition, both featuring V-Max bullets. The test reveals similar penetration depths between 6 and 7 inches, with fragmentation observed in both. The CCI ammunition showed slightly heavier recovered bullet weights and a marginally larger expanded diameter, potentially due to its slightly lower advertised velocity.

Quick Summary

In a ballistic gel test, both CCI and Hornady .17 Mach 2 V-Max ammunition demonstrated similar terminal performance, achieving penetration depths between 6 and 7 inches with observed fragmentation. CCI's ammunition yielded slightly heavier recovered bullet fragments on average, while Hornady was marginally faster in actual chronograph readings.

Frequently Asked Questions

What is the difference between .17 Mach 2 and .17 HMR ammunition?

The .17 Mach 2 (HM2) uses a .22 Long Rifle case necked down to .17 caliber. In contrast, the .17 HMR is based on a .22 Magnum case necked down to .17 caliber, making it a larger and more powerful cartridge.

How did CCI and Hornady .17 Mach 2 perform in ballistic gel?

Both CCI and Hornady .17 Mach 2 V-Max bullets showed similar terminal performance in 10% ballistic gelatin, achieving penetration between 6 and 7 inches with fragmentation. Recovered CCI fragments were slightly heavier on average.

What are the advertised velocities for CCI and Hornady .17 Mach 2?

CCI advertises its .17 Mach 2 ammunition at 2010 feet per second, while Hornady advertises its version at 2100 feet per second. Actual chronograph readings in the test were slightly above these advertised velocities.

What was the expanded diameter of the .17 Mach 2 bullets after passing through ballistic gel?

The expanded diameter of the recovered .17 Mach 2 bullets was measured to be approximately 0.25 to 0.30 caliber. The CCI ammunition showed a slightly larger expanded diameter compared to the Hornady.
