300 AAC – 220 gr OTFB – Remington (28430) – 200 Rounds

The .300 AAC Blackout 220 gr OTFB Remington (28430) load delivers quiet, controlled performance for shooters operating subsonic platforms. It uses an Open Tip Flat Base (OTFB) projectile engineered for stability at low velocities. Because of this, the load excels in suppressed shooting, tactical training, and specialty applications where sound reduction and consistency matter. Shooters running suppressors or short-barreled rifles frequently choose heavy subsonic .300 AAC loads for reliable cycling and predictable flight.

Remington loads the 28430 to a muzzle velocity of 940 fps and a muzzle energy of 432 ft-lbs from standard test barrels. These ballistics keep the projectile below the speed of sound 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 subsonic speeds. Consequently, this load maintains consistent point-of-impact and reliable accuracy during close- to mid-range engagements.

This product ships as 20 rounds per box and 10 boxes per case (200 rounds total). Therefore, buyers receive sufficient volume for dedicated suppressed training, function testing, or system validation. Remington manufactures this ammunition with reloadable brass cases and non-corrosive Boxer primers, ensuring dependable ignition and smooth cycling in properly tuned .300 AAC Blackout firearms. Furthermore, Remington’s quality standards emphasize uniform velocities and reliable feeding across compatible AR-platform rifles.

While optimized for suppressed and subsonic use, the .300 AAC Blackout 220 gr OTFB Remington (28430) also serves shooters who require predictable recoil, controlled performance, and consistent results from specialized platforms.
