Description

One of the Heaviest Loads Available for the Platform

The Omega was developed for shooters who want to maximize projectile weight within the practical limits of the 12.7x42mm platform. At 700gr Omega, this load represents an extreme approach to big-bore AR performance, emphasizing momentum and projectile mass rather than velocity.

This is Steinel’s heaviest 12.7×42 cartridge and it is compatible with Alexander Arms .50 BEOWULF® upper receivers.  This brute of a projectile allows the round to cycle, lock open on empty, and behave the way a heavy-hitting AR-15 round should.  This shoulder-mounted artillery round hits on both ends.  It is a thrill to chuck this mass of lead downrange.

This 50 Beowulf 700 grain load combines tremendous projectile weight with subsonic-capable velocity to create a uniquely hard-hitting cartridge suitable for shooters seeking powerful terminal performance, deep penetration, and maximum momentum from a modern sporting rifle platform.

Do you want to take advantage of the AR-15’s potential?  Now there’s a load that truly allows you to capitalize on that mystical 1/2″ bore diameter.

Optimized for Suppressed Shooting

This load was engineered around subsonic velocity performance and functions well in properly configured rifles with or without suppressors. The combination of a 700gr Omega hard cast projectile and approximately 900 FPS muzzle velocity provides a distinctive shooting experience that many big-bore enthusiasts seek when building suppressed rifle systems.

50 Beowulf 700 Grain Performance

For shooters seeking maximum mass and impact, this 50 Beowulf 700 grain load stands at the extreme end of the spectrum. Heavy-for-caliber projectiles like this are purpose-built for those who want to push the limits of what the platform can deliver offering exceptional momentum and a uniquely powerful shooting experience.

Built for Enthusiasts of Big-Bore AR Platforms

The 12.7x42mm platform has developed a strong following among shooters who appreciate large-caliber AR rifles and the unique performance characteristics they offer. This load was created for those enthusiasts who want something beyond conventional ammunition.

Whether used for recreational shooting, suppressor-focused builds, or simply exploring the capabilities of a half inch bore diameter, the Omega delivers a shooting experience that stands apart from typical rifle cartridges.
