300 AAC Blackout – 220 gr OTM – Black Hills (D300WHISPERN2) – 500 Rounds

The .300 AAC Blackout 220 gr OTM Black Hills (D300WHISPERN2) load delivers controlled subsonic performance for shooters who prioritize consistency, suppression, and precision at short to mid distances. It uses an Open Tip Match (OTM) projectile designed for balance and stability at low velocities. Because of this, the load suits buyers running suppressed rifles and short-barreled platforms. Many shooters choose heavy OTM bullets to maintain accuracy while staying below the sound barrier.

Black Hills loads the D300WHISPERN2 to a muzzle velocity of 1,050 fps and a muzzle energy of 539 ft-lbs from standard test barrels. These ballistics keep the round subsonic under typical conditions. As a result, shooters experience reduced report and minimal sonic crack when paired with a suppressor. In addition, the 220-grain bullet weight enhances momentum and stability at low speeds. Consequently, the load delivers predictable point-of-impact and reliable grouping during suppressed use.

This product ships as 25 rounds per box and 20 boxes per case (500 rounds total). Therefore, buyers receive substantial volume for dedicated suppressed training, function testing, and system validation. Black Hills manufactures this ammunition with premium reloadable brass cases and non-corrosive Boxer primers, ensuring consistent ignition and smooth feeding. Furthermore, Black Hills’ strict quality controls emphasize uniform velocities and dependable performance across extended shooting sessions.

While optimized for subsonic and suppressed applications, the .300 AAC Blackout 220 gr OTM Black Hills (D300WHISPERN2) also appeals to shooters who want repeatable recoil and consistent accuracy. Ultimately, it delivers quiet operation, stable flight, and trusted Black Hills craftsmanship in a purpose-built subsonic load.
