Federal hunting ammunition with lead-free Barnes TSX bullet. TSX = Triple Shock X lead-free bullet, developed in 2003 with the distinctive transverse grooves. This technology results in less running stress and improves precision.

Expansion to double the caliber size, almost 100% residual weight and excellent precision characterize these lead-free deformation bullets made of 100% copper. Several transverse grooves in the bullet reduce the pressure in the barrel, which means it is gentle on the barrel and ensures cut hairs at the point of impact. The mushrooming in 4 "flags" ensures high energy release in the game body and always ensures a reject.
