5.45x39 7N6 Ballistics Gel Test With A SBR'd Krink (HD)

Published on May 24, 2015
Duration: 3:56

This video provides an expert-level ballistics gel test of 5.45x39 7N6 ammunition fired from a short-barreled rifle (SBR'd Krink) with an 8.5-inch barrel. The presenter, Mrgunsngear, demonstrates extensive experience with this ammunition, detailing its consistent tumbling behavior and penetration depth in FBI-spec gel. The test includes chronograph readings and visual evidence of the bullet's terminal performance, highlighting why 7N6 is known for its effectiveness.

Quick Summary

An expert ballistic gel test of 5.45x39 7N6 ammunition from an SBR'd Krink (8.5" barrel) shows an average velocity of ~2550 FPS. The ammunition consistently tumbles in FBI-spec gel, exiting at 14 inches, a characteristic that contributes to its combat effectiveness and earns it the nickname 'poison bullet'.

Frequently Asked Questions

What is the typical performance of 5.45x39 7N6 ammunition from a short-barreled rifle?

From an 8.5-inch barrel, 5.45x39 7N6 ammunition averages around 2550 FPS and is known to consistently tumble in ballistic gel, exiting around 14 inches. This tumbling action contributes to its combat effectiveness.

How does barrel length affect the velocity of 7N6 ammunition?

A shorter 8.5-inch barrel yields approximately 2550 FPS for 7N6. The presenter estimates that a standard 16-inch barrel would increase this velocity to around 2950 FPS, leading to more aggressive terminal ballistics.

What is the significance of 7N6 ammunition's tumbling behavior?

The consistent tumbling of 7N6 projectiles in soft tissue creates larger wound channels, significantly enhancing its effectiveness in combat scenarios. This characteristic has led to its nickname, the 'poison bullet'.

What equipment was used for the 7N6 ballistic gel test?

The test utilized an SBR'd Krink with an 8.5-inch barrel, 5.45x39 7N6 ammunition, a Chrony F-1 chronograph for velocity measurements, and FBI-standard 6x6x16 inch ballistic gel blocks.
