Underwood 300 Aac 125gr Bt - 20rd 10bx/cs

The Underwood 300 AAC 125gr BT ammunition represents a precision-engineered cartridge purpose-built for suppressed rifle systems and subsonic duty cycles where terminal performance demands reliability without compromise. Designed for tactical professionals, military operators, and serious civilian shooters, this round delivers consistent ballistic performance in the .300 Blackout platform—America's most effective intermediate suppressor-compatible cartridge. The 125-grain projectile weight strikes the critical balance between subsonic velocity compliance and functional penetration depth required in real-world defensive and professional applications.

Each round pairs a ballistic tip spitzer projectile with brass casing, loaded to a consistent muzzle velocity of 2,250 feet per second, generating 1,405 foot-pounds of muzzle energy at the point of discharge. The ballistic tip construction ensures reliable expansion and energy transfer upon impact while maintaining the subsonic velocity threshold critical for suppressor function and noise reduction—a defining advantage over full-power rifle rounds in tactical environments. Brass casings provide superior reload longevity and reliability in semi-automatic and bolt-action platforms alike, making this ammunition suitable for extended field operations and training cycles where ammunition accountability matters.

This ammunition performs optimally in AR-15 pattern rifles chambered in .300 Blackout, bolt-action hunting rifles, and precision rifle systems where subsonic operation is required or preferred. Law enforcement tactical teams, military special operations units, and professional security operators benefit from the predictable ballistics and suppressed signature this round provides during close-quarters engagement and precision work. Each box contains 20 rounds, with 10 boxes per case, facilitating efficient inventory management and bulk procurement for agencies and commercial shooting facilities requiring consistent, field-tested ammunition specifications.
