The .22 PPC / 5.7x38mm is a centerfire rifle cartridge developed in 1974 by Dr. Louis Palmisano and Ferris Pindell, primarily as a benchrest cartridge. The cartridge is based on the 5.6×39mm (.220 Russian) case which is a necked-down version of the 7.62×39mm Soviet military cartridge. Several companies have made custom guns in this caliber, however no major companies did until 1993, when Ruger announced their No. 1 V and M77 varmint rifles in this caliber.
