Our Target and Tactical bullets are designed with thicker jackets that withstand more stress before bullet degradation occurs. A target or tactical shooter generally fires multiple rounds in a row, causing the barrel to heat up and more stress on bullet. To keep performance high, we give these bullets thicker jackets.
Our Varmint and Hunting bullets have slightly thinner jackets. This means that the bullet will expand more effectively, creating a large wound cavity that devastates the animal using hydrostatic shock. Hunters generally shoot 1-3 bullets at a time, so bullet degradation is not as much of a concern as expansion.
