Big Brother is our 220 gr subsonic solid copper projectile paired with the NAS3 casing. This the top of the line for defensive and hunting subsonic 300 blackout ammunition. Requires 1:5 or 1:7 twist to stabilize.
The Nas3 casing, featuring Shell Shock's innovative Nas3 technology, is up to 50% lighter than traditional brass cases, improving accuracy and shot consistency. The cases offer superior lubricity and eliminate concerns of clogging, fouling, or wear on the breach and ejector mechanisms. The nickel-alloy cylinder enhances durability with 2x the tensile strength and elasticity of brass, offering greater corrosion resistance and ensuring cooler, easy-to-handle ejection.
The "Big Brother" is engineered to literally be the Big Brother to 'Slow Papi'; this is for shooters who demand the best in performance and reliability, offering unparalleled power, precision, and that satisfying lack of noise, all in a lightweight, cutting-edge design. Paired with a projectile designed for maximum expansion and superior terminal ballistics, this is the most devestating subsonic 300 AAC Blackout round on the market.
