Description

Hornady Superformance ammunition addresses the performance ceiling of conventional propellant technology by using progressive Hornady Superformance propellants that build pressure more gradually, unlocking higher muzzle velocities without exceeding standard chamber pressure limits. In 22 ARC, this translates to a 70-grain CX bullet leaving the muzzle at 3125 fps — a gain of 100 to 200 fps over loads using conventional powders — with 1518 ft-lbs of muzzle energy. The propellant formulation is also engineered for low temperature sensitivity, delivering consistent velocity across a broad range of environmental conditions, which is a common failure point of older powder technologies.

The 70-grain CX (Copper alloy eXpanding) bullet is a monolithic design that eliminates the lead core entirely, producing reliable, controlled expansion across a wide range of impact velocities while retaining nearly all its original mass. This makes the load effective for hunting applications where deep penetration and high weight retention are required. Hornady specifies this load is safe for use in all firearm types including semi-automatics, lever guns, and pump actions. Cases and primers are selected for consistent dimensional tolerances and reliable ignition. Ballistics data was developed using a 24″ test barrel.
