This video showcases the development and testing of a new wildcat cartridge, dubbed the '50 Alaskan Rim Job' or '50 Arch,' designed to fire 50 BMG bullets at subsonic velocities. The creator demonstrates its destructive potential against various barriers, comparing it to the 8.6 Blackout. The video highlights the cartridge's performance in penetration and impact, featuring extensive testing on lumber, steel, sand, and concrete, with a focus on its subsonic capabilities.

Quick Summary

The '50 Alaskan Rim Job' or '50 Arch' is a new wildcat cartridge designed to fire heavy 50 BMG bullets, like 660-grain rounds, at subsonic velocities. It demonstrates superior power and penetration compared to cartridges like the 8.6 Blackout, successfully penetrating lumber, steel, sand, and concrete barriers during extensive testing.

Frequently Asked Questions

What is the new wildcat cartridge called and what makes it unique?

The new wildcat cartridge is called the '50 Alaskan Rim Job' or '50 Arch' for short. Its uniqueness lies in its ability to fire heavy 50 BMG bullets, such as 660-grain rounds, at subsonic velocities, offering immense power and penetration.

How does the 50 Arch cartridge compare to the 8.6 Blackout in terms of performance?

The 50 Arch significantly outperforms the 8.6 Blackout in raw power and penetration. While the 8.6 Blackout fires 300-350 grain bullets subsonically, the 50 Arch fires much heavier 660-grain bullets at similar subsonic speeds, demonstrating greater destructive capability against barriers.

What kind of barriers was the 50 Arch cartridge tested against?

The 50 Arch was tested against a variety of challenging barriers including pressure-treated lumber, 8-inch thick steel plates, 6 inches of sand, and 1.57-inch thick concrete pavers. It also penetrated multiple thicknesses of mild steel, up to 3/8 inch.

What was the muzzle energy of the 50 Arch cartridge during testing?

During concrete testing, the 50 Arch cartridge, firing a 660-grain round, produced over 1600 foot-pounds of muzzle energy. This is nearly double the muzzle energy of the 8.6 Blackout with a 342-grain bullet, which was around 850 foot-pounds.
