The 6mm PPC (Palmisano & Pindel Cartridge), or 6x38 PPC as it is more often called, is a centerfire rifle cartridge used almost exclusively for benchrest shooting. It is one of the most accurate cartridges available at distances of up to 300 meters. This cartridge's accuracy is produced by a combination of its posture, being only 31 mm (1.22 in) long, and shoulder angle of 30 degrees. Its primary use has been benchrest shooting matches since the 1980s.
