For hunters who want heavy bullet performance at subsonic speeds, the Hornady Subsonic 45-70 Govt Rifle Ammunition Brass 20 Rounds 410 Grain Sub-X delivers controlled expansion and reliable impact without breaking the sound barrier. Built specifically for suppressed use and quiet hunting applications, this load combines classic 45-70 authority with modern bullet engineering.

At the center of this cartridge is the 410 grain Sub-X bullet. Designed to perform at subsonic velocities, the Sub-X features a polymer tip and internal construction engineered to initiate expansion at lower impact speeds. The heavy 410 grain weight enhances momentum and penetration, while the bullet’s design helps ensure dependable terminal performance on medium game. It’s built to expand consistently where traditional bullets may fail at reduced velocities.

With a muzzle velocity of 1075 feet per second, this load stays below the speed of sound in most conditions, making it ideal for suppressed rifles. Despite its subsonic speed, it delivers 1052 foot-pounds of muzzle energy, providing meaningful downrange authority while maintaining a quieter report and reduced recoil impulse.

Each round is loaded into durable brass casings and matched with dependable centerfire Boxer primers for consistent ignition and smooth function. The brass cases are fully reloadable, offering long-term value for shooters who prefer to build their own loads. Hornady’s strict quality standards ensure uniform powder charges and precise bullet seating for consistent accuracy and reliable cycling.

Packaged in a 20 round box, this Hornady Subsonic 45-70 Govt 410 Grain Sub-X ammunition is built for hunters who demand quiet performance, heavy bullet penetration, and dependable expansion in the field.
