Rem Hypersonic 450 Bm 300gr 20/200 - REM27941

The Remington Hypersonic 450 BM 300gr ammunition delivers controlled-expansion performance built on seven decades of field-proven big game cartridge engineering. Loaded with Remington's Core-Lokt bullet design, this round combines tapered copper jacket technology with a solid lead core to achieve reliable 2X expansion, maximum weight retention, and consistent ballistic performance downrange—making it a proven choice for serious hunters pursuing medium to large game across diverse terrain and conditions.

Each 300-grain projectile is engineered to maintain structural integrity from impact through full penetration, delivering energy transfer without fragmentation or deflection from bone and heavy muscle. The Core-Lokt architecture has been refined through more than 75 years of field applications, making it the foundation of Remington's reputation in controlled-expansion ammunition. This weight and velocity combination is particularly effective in medium-range hunting scenarios where shot placement and reliable bullet performance determine success in the field.

Hunters selecting the Hypersonic 450 BM are targeting game species that demand heavy, deep-penetrating ammunition—elk, moose, and large bears in regions where this caliber is legal and appropriate. The 300-grain loading prioritizes momentum and controlled expansion over velocity, making it suitable for both open-country and brush hunting where follow-up accuracy matters. Serious shooters building a hunting battery appreciate Remington's consistency in loading and quality control, which translates to predictable point-of-impact shifts between factory loads and repeatable performance across multiple hunting seasons.

In the broader context of factory big game ammunition, the Hypersonic line represents Remington's direct response to magnum cartridge hunters who reject premium-priced alternatives without sacrificing terminal performance. The Core-Lokt bullet remains the industry standard against which controlled-expansion designs are measured—a distinction earned through consistent field results rather than marketing claims. For hunters prioritizing proven reliability and lethal efficiency over cost-cutting, this ammunition has earned its position as America's most widely used big game load across multiple continents and hunting conditions.
