Duration: 12:57

This video provides an expert-level comparison of the penetration capabilities of the .50 Cal SLAP (Saboted Light Armor Penetrator) Tracer round against the Hornady 750gr A-MAX. The host, demonstrating high authority and technical expertise, uses a Desert Tech HTI rifle and a chronograph to test various thicknesses of mild steel. Key takeaways include the surprising effectiveness of the A-MAX against thinner steel and the unexpected stopping power of 1.5" mild steel against the SLAP round at 50 yards, despite its armor-piercing design. Safety precautions, including sabot strike prevention, are emphasized.

Quick Summary

In testing with a Desert Tech HTI at 50 yards, the M903 SLAP round was surprisingly stopped by 1.5 inches of mild steel, failing to penetrate despite its armor-piercing design and tungsten core. The Hornady 750gr A-MAX also showed significant impact but was stopped by 5/8 inch steel.

Frequently Asked Questions

What is the difference between a .50 Cal SLAP round and a standard .50 BMG round like the Hornady A-MAX?

A .50 Cal SLAP (Saboted Light Armor Penetrator) uses a smaller tungsten penetrator within a sabot to achieve higher velocities and penetration against armor. A standard .50 BMG round like the Hornady 750gr A-MAX is a heavier, monolithic bullet designed for long-range accuracy and terminal energy.

How much mild steel can a .50 Cal SLAP round penetrate?

In testing with a Desert Tech HTI at 50 yards, the M903 SLAP round was surprisingly stopped by 1.5 inches of mild steel, failing to penetrate despite its armor-piercing design and tungsten core.

What rifle was used to test the .50 Cal SLAP and Hornady A-MAX rounds?

The testing was conducted using a Desert Tech HTI rifle, a .50 BMG anti-materiel rifle known for its relatively lighter weight compared to other rifles in its class.

Are there any safety concerns when firing SLAP ammunition?

Yes, a critical safety concern with SLAP rounds is the potential for the sabot to strike and damage muzzle devices. It is recommended to remove muzzle brakes or suppressors before firing SLAP ammunition.
