2 of the most BRUTAL Rounds In Existence | (Not your standard 300 Win Mag)

Published on April 15, 2025
Duration: 14:36

This video details a test of custom-loaded 300 Winchester Magnum ammunition featuring M2 black tip armor-piercing and silver tip armor-piercing incendiary (API) bullets against AR-550 steel targets. The instructor, Josh, meticulously records velocities using a chronograph and observes impact points on paper targets before engaging steel at 110 yards. While the silver tip API rounds created significant impact marks and soot, they did not penetrate the CZone steel. The M2 black tip rounds, despite expectations, also failed to penetrate the AR-550 steel, leaving only minor chips, which the instructor attributes to the steel's strength and the target bracket's engineering.

Quick Summary

Custom-loaded 300 Winchester Magnum ammunition, including M2 black tip armor-piercing and silver tip API rounds, was tested against AR-550 steel targets. Velocities ranged from 2915 to over 3000 fps. Neither round penetrated the steel, demonstrating the target's resilience and the importance of proper handloading safety.

Frequently Asked Questions

What types of armor-piercing ammunition were tested in 300 Winchester Magnum?

The video tested custom-loaded 300 Winchester Magnum ammunition featuring M2 black tip armor-piercing rounds and silver tip armor-piercing incendiary (API) rounds. These were specifically loaded to test their capabilities against hardened steel targets.

Did the 300 Win Mag armor-piercing rounds penetrate AR-550 steel targets?

No, neither the M2 black tip armor-piercing nor the silver tip API rounds fired from 300 Winchester Magnum at 110 yards were able to penetrate the AR-550 steel targets. They caused surface damage and minor chips but did not go through.

What velocities were achieved with the tested 300 Win Mag loads?

The velocities recorded for the custom-loaded 300 Winchester Magnum ammunition ranged from approximately 2915 feet per second for the black tip rounds to over 3000 feet per second for some of the silver tip API rounds.

What are the key safety considerations for handloading heavy loads?

When handloading, it's critical to analyze case signs like primer flattening or fracturing to avoid over-pressurization. Pushing for maximum speed without proper analysis can lead to dangerous conditions and reduced accuracy.
