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.{{Cite web |title=Lee Precision, Inc. - 22 PPC |url=https://leeprecision.com/22-ppc |access-date=2024-08-28 |website=leeprecision.com}} 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.
Changes from the .220 Russian cartridge
The changes from the .220 Russian into the .22 PPC include a 10-degree body taper and 30-degree shoulder angle, as well as expanding the neck to accept the standard {{convert|.224|in|mm}} diameter bullet used in the U.S. Cases are made in Finland by Sako or in Sweden by Norma and use Small Rifle primers. Although the .22 PPC is a short, rather stubby case (only {{convert|1.51|in|mm}} long), it nevertheless develops ballistics superior to some larger, longer cartridges such as the .222 and .223 Remington. The 52-grain bullet can be pushed out of the muzzle at over {{convert|3500|ft/s|m/s}}, placing the .22 PPC in the varmint and small game class. A 1 in 14-inch (1 in 355 mm) twist has become pretty much standard for these rifles although 1 in 12-inch (1 in 305 mm) twist will sometimes be found, depending on the load and bullet weight.
