Barnes Bullets Pioneer Brass .357 Mag 140 Grain 20-Rounds FNTSX

Barnes Pioneer .357 Magnum Features The Triple Shock X bullet is renowned for its all-copper construction which not only leads to significant weight retention but also promotes deeper penetration and controlled expansion. This makes the 140-grain TSX bullet highly effective in delivering lethal performance against larger threats and game animals ensuring clean and ethical kills due to its consistent behavior upon impact. The TSX design includes multiple grooves in the bullet shank reducing barrel fouling and increasing accuracy. This is especially beneficial for maintaining the performance of the firearm over prolonged shooting sessions. The bullet s ability to expand to nearly twice its original diameter upon impact while retaining virtually all its mass enhances its terminal ballistics making it an excellent choice for critical applications.
