Umarex USA offers an big-bore .50-Caliber Air Rifle, which it claims is the world’s most powerful air gun. The new Umarex Hammer can launch a 550 grain slug at 760 fps, delivering an impressive 705 foot-lbs of energy at the muzzle. That energy total rivals a 10mm Auto Cartridge (220 grainer at 1200 fps). Not bad for an air rifle with an $815.99 MSRP.

With lighter projectiles, the Umarex Hammer also delivers fairly high velocities — it can drive a 200 grain lead projectile at 1055 fps. That’s equivalent to a .45 ACP +P load. The design team at Umarex say this air rifle has the power to take deer and other game — when the animals are close enough.

The Umarex Hammer has features you might find on a modern centerfire rifle: 29.5″ button-rifled barrel, straight-pull bolt, 8.5″ Picatinny rail, and quality trigger with 3-lb pull. The Made-in-USA Hammer is powered by an on-board, 24-cubic-inch carbon fiber cylinder filled at 4500 psi. The Hammer incorporates a Lightspeed™ valve and precision regulator that launches the projectiles with a 3000 psi air blast. Umarex says the Hammer is quite accurate — capable of putting three, 350- grain lead slugs in an inch at 50 yards.
