CCI TNT .17HMR vs .22WMR Ballistic Gel Test & Review

Published on March 26, 2024
Duration: 14:28

This video compares the CCI TNT .17 HMR and .22 WMR ammunition through ballistic gelatin at close range. The .17 HMR demonstrated better penetration with its base carrying further, while the .22 WMR fragmented more readily, resulting in shallower penetration. The test also included a brief evaluation through four layers of denim, showing similar fragmentation patterns.

Quick Summary

In ballistic gelatin tests, CCI TNT .17 HMR generally shows better penetration, with its base carrying further after fragmentation. The .22 WMR variant tends to fragment more rapidly and extensively, resulting in shallower penetration, typically around 3 inches. This difference is attributed to the larger expanded diameter of the .22 WMR fragments creating more resistance.

Frequently Asked Questions

How does CCI TNT .17 HMR compare to .22 WMR in ballistic gelatin?

In ballistic gelatin tests, the CCI TNT .17 HMR generally shows better penetration, with its base carrying further after fragmentation. The .22 WMR variant tends to fragment more rapidly and extensively, resulting in shallower penetration, typically around 3 inches.

What is the typical fragmentation pattern of CCI TNT .22 WMR in ballistic gelatin?

The CCI TNT .22 WMR ammunition consistently fragments rapidly upon impact with ballistic gelatin. This fragmentation results in numerous small segments scattering widely, limiting the overall penetration depth to approximately 3 inches.

Does rifle action type (bolt vs. semi-auto) affect .17 HMR and .22 WMR velocity?

The difference in velocity between a semi-automatic .22 WMR and a bolt-action .17 HMR rifle is negligible, typically around 1%. This minor difference does not significantly impact ballistic performance in tests like these.

How does denim affect the performance of CCI TNT .17 HMR and .22 WMR in ballistic gelatin?

Testing CCI TNT .17 HMR and .22 WMR through four layers of denim before impacting ballistic gelatin did not significantly alter their terminal performance. Both calibers exhibited similar fragmentation patterns and penetration depths as they did without the denim.
