This video tests the penetration capabilities of the .300 Winchester Magnum armor-piercing round against various steel thicknesses and RMA's XRT Special Threat Plate. The Swiss P AP round successfully penetrated 1.25 inches of mild steel and the XRT plate, demonstrating significant armor-piercing power. While the XRT plate stopped the standard MK 248 Mod 1 round, it was defeated by the AP variant. The test concludes that the .300 Win Mag AP round is highly effective against most common barriers.

This video series aims to replicate the performance of the MK 248 Mod 1 military ammunition. Part 1 focuses on the 300 Winchester Magnum caliber and the use of the 220gr Sierra Match King projectile. The creator intends to build a new reloading series around this specific endeavor, offering a deep dive into achieving military-grade performance from a civilian reloading bench.
