This centerfire rifle cartridge is a relatively new development, designed for long-range target shooting and hunting. It is based on the .30 TC cartridge, necked down to accept a .257-inch diameter bullet. Common bullet weights range from 75 to 131 grains. This specific configuration offers a flatter trajectory and reduced recoil compared to other cartridges with similar ballistic performance.
The inherent accuracy and efficiency of this cartridge make it highly desirable for competitive shooting disciplines and ethical hunting practices. Its reduced recoil contributes to improved shooter comfort and control, facilitating consistent shot placement. Introduced in 2007, it quickly gained popularity amongst long-range enthusiasts and professional marksmen. This rapid adoption is a testament to its effectiveness and the tangible advantages it offers over existing cartridges.
