Black Hills ammunition introduced the 50 grain TSX last year and it has been an overwhelming success as a premium “barrier blind” defense and duty load but some folks really wanted something heavier. The Optimized 5.56mm 62 TSX load is designed for use in all rifles with a twist rate of 1/9” and faster, including short barreled rifles. It is flash suppressed for use in low light situations. This load opens up immediately upon impact to over 50 caliber and penetrates to 20” in ballistic gel tissue simulant, while creating a wound channel over 5” in diameter. This 5.56mm ammunition is loaded to pressures higher than commercial .223 ammunition in order to provide maximum performance and should be used only in suitably chambered firearms.
