Duration: 20:54

This guide details a ballistic gelatin penetration test procedure, as demonstrated by Karl from Tactical Rifleman. The test evaluates how various rifle rounds, including M855 Green Tip, M855A1, 7.62x39mm, .300 Blackout, and M118LR, perform after passing through common building materials like brick and concrete blocks. The expert-level instruction emphasizes understanding terminal ballistics and over-penetration risks through consistent testing methods.

Quick Summary

Expert Karl from Tactical Rifleman conducted a penetration test evaluating M855 Green Tip, AK, .300 Blackout, and .308 rounds through brick and concrete. Red brick proved highly effective, stopping all rounds, while hollow concrete blocks were penetrated by higher-performance rounds like M855A1 and .308. Ballistic gelatin was used to measure terminal effects post-barrier.

Frequently Asked Questions

What rifle rounds were tested for penetration through common building materials?

The test included M855 'Green Tip' (5.56mm 62gr), M855A1 (steel tip, copper core), 7.62x39mm AK steel core, .300 Blackout (Barnes 110gr TAC-TX), and M118LR (7.62x51mm 175gr sniper round).

How did red brick perform as a barrier against rifle rounds?

Red brick proved to be an exceptional barrier, stopping all tested rounds, including the M118LR .308 sniper round, in the penetration test. The brick alone prevented any rounds from reaching the ballistic gelatin behind it.

Which rounds were most effective against hollow concrete blocks?

The M855A1 5.56mm round and the M118LR 7.62x51mm (.308) round demonstrated significant capability in penetrating hollow concrete blocks, with the M855A1 showing improved performance over the standard M855 Green Tip.

What is the purpose of using ballistic gelatin in penetration tests?

Ballistic gelatin, like Clear Ballistics, is used to simulate soft tissue. It provides a consistent medium to gauge a projectile's performance, penetration depth, and terminal effects after passing through barriers, aiding in lethality assessment.
