22 Super Jet

Historical Notes:

The 22 Super Jet was developed by gun writer Dan Cotterman and the data first published in the July, 1962 issue of Gun World magazine. It is based on the 22 Remington Jet, which is fire formed in the 22 Super Jet chamber. It can also be formed from 357 Magnum brass cases because it is essentially a 357 Magnum necked down to 22. There are several versions of this cartridge, but they are all very similar. The Ackley version, or Improved Jet, and the 22 Sabre Cat by Christian Helbig are practically identical,  and loading data can be used interchangeably with the same results. These cartridges are also very similar in performance to the 218 Mashburn Bee. Their primary purpose is to provide a rimmed case for use in single shot rifles.

General Comments:

These relatively small 22 centerfire cartridges are ballistically superior to the factory 218 Bee and will push the 45 grain bullet an extra 200 to 300 feet per second in muzzle velocity. They are effective cartridges for their intended purpose, but the 218 Mashburn Bee will do as well or better, and is less trouble to make. The one advantage they have over the 218 Mashburn Bee is that the 357 Magnum brass is plentiful and cheap. The Super Jets are good 200 yard plus varmint cartridges.
