Sig Sauer Max Expansion .300 Blackout Subsonic 194 gr Hollow Point - 20 Rd Box

Sig Sauer Max Expansion .300 Blackout Subsonic 194 gr Hollow Point - 20 Rd Box

Engineered for extreme reliability, maximum terminal performance, and whisper-quiet operation, SIG Sauer .300 Blackout 194gr Max Expansion Subsonic Ammunition delivers defensive-grade consistency for suppressed .300BLK short-barrel rifles and carbines. Purpose-built to overcome the traditional terminal limitations of subsonic ammunition, this round features a specialized 194-grain projectile designed to expand rapidly and reliably at velocities below the speed of sound, creating devastating wound channels without requiring high velocity.

Optimized for suppressed platforms, each round is loaded into premium reloadable brass casings with precision-metered propellants to ensure consistent, subsonic flight without crossing the supersonic threshold. Generating 430 ft-lbs of muzzle energy and a high G1 ballistic coefficient of 0.545 out of a standard 9-inch test barrel, this 20-round box of 300BLK Max Expansion ammo is an ideal choice for home defense, tactical applications, and suppressed hunting where hearing safety and stopping power are critical.

Features

194-Grain Max Expansion Bullet:
Specially engineered projectile design expands reliably at subsonic velocities where traditional expanding bullets fail, maximizing tissue destruction and energy transfer.

Whisper-Quiet Subsonic Velocity:
Loaded to maintain a consistent 1,000 fps muzzle velocity out of a 9.0" test barrel, eliminating the sonic crack for superior sound suppression.

High G1 Ballistic Coefficient (0.545):
Heavy 194-grain profile boasts an impressive 0.545 G1 BC, ensuring aerodynamic stability, wind resistance, and energy retention downrange.

Optimized for Suppressed 300BLK Systems:
Formulated to cycle reliably in both manual and gas-operated suppressed 300BLK rifles without generating excessive fouling or blowback.

Premium Reloadable Brass Casings:
Built with high-quality factory-fresh brass cases, non-corrosive primers, and clean-burning powders for smooth feeding, extraction, and long case life.

Military-Grade Reliability Standards:
Manufactured under SIG Sauer’s strict quality control protocols to ensure lot-to-lot velocity consistency and mission-ready performance.
