Umarex SpeedBelt ARX Muzzleloader Bullets

Umarex SpeedBelt ARX Muzzleloader Bullets

Umarex, the world’s largest manufacturer of over-the-counter firearm replicas (its products include airguns, airsoft guns and ammunition, blank-firing guns, optics, knives and tools, flashlights, headlights, slingshots, blowguns, pepper spray, handcuffs, batons, crossbows, and other innovative products), recently entered the muzzleloader market by partnering with Inceptor Ammunition to offer the new 180-grain SpeedBelt ARX Muzzleloader Bullets. These projectiles feature the new SpeedBelt sabot from Umarex and the fluted ARX bullet design that is produced by Inceptor Ammunition and owned by Quantum Ammunition LLC.

According to Inceptor Ammunition CEO Ron Embree, “When paired with the Umarex SpeedBelt sabot, ARX bullets deliver extreme energy transfer to targets, reduced recoil, and exceptional accuracy and stopping power.”

The ARX bullet is a non-expanding, non-lead, injection-molded polymer-copper matrix projectile whose flutes provide tremendous terminal performance. The bullet delivers extreme energy transfer laterally and forward to game, producing excellent knockdown power. The distinctive flutes create tremendous wound channels, providing hydraulic displacement that rivals and typically exceeds traditional expanding bullets. According to Umarex, “After entering soft tissue, the specially designed grooves in the nose of the non-expanding ARX bullet constrict, pressurize, and eject fluid at 1.5 to two times the directional speed of the bullet. These bullets are lighter, faster, and hit harder.”

The SpeedBelt sabot’s outside diameter measures 0.509 inch at the base cup and tapers to 0.504 inch at the nose of the cup. The sabot’s base cup is made of polymers that withstand the blast of the muzzleloader, and the powder’s blast flares the cup to create engagement with the rifling of the rifle’s barrel. Designed for use in .50-caliber muzzleloading rifles, the innovative SpeedBelt sabot paired with the ARX bullet is intended to be used with a 100-grain powder charge, and 100 grains of Pyrodex produces 1,845 fps and 1,450 ft-lbs of energy at 15 yards in company tests.


The lead-free ARX bullet is a universal hunting projectile. It helps reduce recoil, and paired with the SpeedBelt sabot, it loads easily in muzzleloaders with no lubrication required.


MSRP: $24.99
