This video from Banana Ballistics provides an expert-level examination of the penetration capabilities of .50 BMG ammunition, including standard ball and M2 Armor Piercing (AP) rounds, against various steel targets. The host, demonstrating high-level firearms enthusiasm and ballistics testing expertise, uses a Desert Tech HTI rifle to test different steel thicknesses and hardness ratings, offering valuable insights into projectile energy, velocity, and material science in terminal ballistics.

Quick Summary

Testing .50 BMG rounds against steel reveals significant differences in penetration. While 5/8-inch mild steel stopped standard ball ammo, M2 AP rounds required thicker or hardened steel. Authentic 1943 M2 AP rounds (approx. 11,358 ft/lbs) were stopped by 1.5-inch mild steel but penetrated 1.25-inch, while AR550 steel offered high resistance.

Frequently Asked Questions

What kind of steel is needed to stop a .50 BMG round?

Stopping a .50 BMG round depends on the ammunition type and steel hardness. While 5/8-inch mild steel stopped standard ball rounds, 1.5-inch mild steel was penetrated by authentic M2 AP rounds. AR550 steel, like a 1/2-inch TA Target, showed superior resistance, only dimpling from high-energy rounds.

What is the difference between standard .50 BMG ball and M2 AP rounds?

Standard .50 BMG ball rounds typically have a lead core, while M2 Armor Piercing (AP) rounds feature a hardened steel core designed for greater penetration. The M2 AP rounds tested were heavier and demonstrated significantly higher penetration capabilities against steel plates.

Which rifle was used to test the .50 BMG rounds?

The video features the Desert Tech HTI (Hard Target Interdiction) rifle, a bolt-action bullpup chambered in .50 BMG. It's noted for its compact design compared to other rifles in its class, such as the Barrett M82A1.

What energy levels were recorded for the .50 BMG rounds?

Standard ball ammunition registered around 10,812 ft/lbs of energy at 2,715 FPS. Authentic 1943 M2 AP rounds were recorded at approximately 11,358 ft/lbs of energy, indicating their potent performance.
