The Remington UMC Mega Pack in 300 Blackout delivers consistent, reliable performance for high-volume training, target practice, and general range applications. Engineered to KFF Defense standards for operational utility, this ammunition provides a cost-effective solution without compromising foundational ballistic integrity.
Key Features
Projectile Design
This load utilizes a 220 grain Open Tip Flat Base (OTFB) projectile. The OTFB design provides consistent bullet geometry and reliable aerodynamic characteristics critical for repeatable accuracy. While distinct from a jacketed hollow point, the OTFB configuration contributes to a stable flight path, particularly beneficial in subsonic configurations often associated with the 300 Blackout cartridge.
Caliber and Application
Chambered in 300 Blackout, this heavy 220gr projectile is optimized for stability and consistent point of impact. It is well-suited for a broad spectrum of rifle platforms, ensuring reliable function during extended training sessions or competitive practice scenarios. Its performance profile supports precise shot placement on steel or paper targets.
Packaging and Value
The Mega Pack configuration provides 200 rounds of loose ammunition, facilitating rapid loading and sustained firing without interruption. This bulk packaging strategy optimizes training efficiency and reduces per-round costs, making it an economically viable option for frequent shooters.
Manufacturing Quality
Loaded in the United States, Remington UMC ammunition maintains stringent quality control protocols to ensure consistent powder charges, primer ignition, and projectile seating, leading to predictable ballistics and dependable cycling across compatible firearms.
