Amazing Performance! 5.56mm Black Hills Optimized 50gr TSX

The 50 gr TSX is a beast, but there has been some speculation in the forums that the barrier blind optimized version from Black Hills won't do well from short barrels. We fire Black Hills 5.56mm Optimized 50 gr TSX from a 10.5" 1:7" twist AR into calibrated 10% ordnance gelatin.
