Published on March 5, 2021
Duration: 10:34

This ballistics gel test compares the 5.56x45mm and 5.45x39mm rifle cartridges. The 5.56mm round demonstrated earlier yawing and significant damage within the first few inches of the gel block. The 5.45mm round maintained a straighter path for longer before yawing, showing slightly more penetration. Both calibers proved effective, with the 5.45x39mm noted for its low recoil.

Quick Summary

The 5.56x45mm round (55gr Winchester) yawed at 2.5 inches, causing early damage, while the 5.45x39mm (59gr Red Army Standard) yawed later at 4-4.5 inches. The 5.45mm achieved 15 inches penetration, compared to 12 inches for the 5.56mm in this test.

Frequently Asked Questions

How does the 5.56mm round perform in ballistics gel compared to the 5.45mm?

In the test, the 5.56mm (55gr Winchester) began yawing around 2.5 inches, causing early damage. The 5.45mm (59gr Red Army Standard) yawed later, around 4-4.5 inches, maintaining a straighter path initially.

Which caliber, 5.56mm or 5.45mm, penetrated deeper in the ballistics gel test?

The 5.45x39mm round achieved 15 inches of penetration. The 5.56x45mm penetrated 12 inches before exiting the side, suggesting it might have reached similar depths if it remained centered.

What are the key differences in terminal ballistics between 5.56mm and 5.45mm?

The 5.56mm tends to yaw and tumble earlier, creating a wider wound channel sooner. The 5.45mm maintains stability longer before yawing, potentially offering deeper penetration in some scenarios.

Is the 5.45x39mm easier to shoot than the 5.56x45mm?

The host noted that the 5.45x39mm cartridge, particularly when fired from an AK-74 platform, offers significantly lower recoil, making it feel 'fun' and potentially easier to manage for follow-up shots.
