Frequently Asked Questions

What are the key terminal ballistics of TulAmmo 7.62x39mm FMJ?

The TulAmmo 7.62x39mm FMJ (122gr) achieves approximately 2,407 FPS and 1,569 ft-lbs of energy. In ballistic gel, it demonstrated significant tumbling, creating a substantial permanent wound cavity without expansion, but also showed considerable over-penetration.

What is the main risk associated with using TulAmmo 7.62x39mm FMJ for self-defense or hunting?

The primary risk is over-penetration. The FMJ projectile tends to tumble rather than expand, leading to deep penetration exceeding 21 inches in ballistic gel tests, posing a danger to targets behind the intended subject.

How does the 7.62x39mm FMJ bullet perform in ballistic gel?

When fired into ballistic gel, the 7.62x39mm FMJ bullet typically tumbles after impact. This tumbling action creates a large permanent wound cavity, but the bullet often continues through multiple gel blocks, indicating high penetration.

Is TulAmmo 7.62x39mm FMJ suitable for hunting?

Yes, it can be effective for hunting medium game due to its tumbling effect creating a significant wound channel. However, hunters must be acutely aware of the over-penetration risk and ensure a safe backstop.
