300 BLACK OUT 190 GR SUB-X CANNED HAM

Canned Ham – 300 Blackout 190gr Sub-X

A Brief History of 300 Blackout

The 300 Blackout was developed to give the AR-15 platform a true .30-caliber option—using standard magazines and parts, while delivering excellent performance both suppressed and unsuppressed. Originally built to meet military needs for a quiet, hard-hitting round in short barrels, it quickly gained popularity among civilian shooters and hunters who wanted subsonic versatility without sacrificing energy on target. Today, it remains the top choice for suppressed shooting and close-range stopping power in a compact package.

About the Hornady 190gr Sub-X

Hornady’s 190gr Sub-X (Subsonic eXpanding) is specifically engineered for subsonic use. Unlike typical heavy bullets that simply poke holes at low speeds, the Sub-X reliably expands thanks to its deep hollow point and patented construction. This means consistent energy transfer at subsonic velocities—making it an excellent choice for hunters and shooters who want more than just quiet shots.

Why Canned Ham is Different

We didn’t just load a heavy bullet and slap a label on it. Canned Ham is the result of careful, time-intensive load development focused on solving the real-world problems common to subsonic 300 Blackout ammo.

This load burns clean, with a powder charge tuned to dramatically reduce or completely eliminate the leftover unburned powder that frustrates many shooters. In most semi-auto, bolt-action, or single-shot platforms, shooters report virtually no muzzle flash, even from short barrels.

This ammo is built to function at true subsonic speeds in barrels from 8 inches up to 16 inches, with some room for longer barrels as well. We use a temperature-stable powder, and each charge is hand-weighed nearly to the kernel, resulting in very low standard deviations and tight, repeatable groups.

From our testing, this ammo performs well in 1:8 twist barrels but really shines in faster twist rates, ensuring the long 190gr Sub-X stays stable all the way to target.

If you want subsonic ammo that reliably shoots 1 MOA—and often better—at 100 yards based on our testing, this is the round for you.
