The ".22 Remington Center Fire Magnum Jet," or ".22 Jet," was introduced in 1961 in the Smith & Wesson Model 53 revolver, with Remington offering ammunition. The revolver, built on the K-Frame, featured a dual firing pin with a selector on the hammer. Steel chamber inserts were available that allowed it to be used with .22 Long Rifle rimfire cartridges, and some guns have been observed with extra cylinders in .22 Winchester Magnum and .22 Long Rifle.

The .22 Jet was based on a necked down .357 Magnum case and advertised to push a 40-grain bullet to 2,460 fps. For reference, early 1960s vintage factory loads were fired, which averaged 1,895 fps from the test gun with a 6-inch barrel.

The Jet’s shoulder is long and sloped, which ultimately caused some problems with case set-back during firing, which could stop cylinder rotation. Keeping chambers clean will help minimize this problem. Also, some older load data was excessive, which likewise compounded the problem.

The Smith & Wesson revolvers featured a .222- to .223-inch groove diameter. Bullets pulled from Remington factory loads measured .2225 inch. Hornady offers a .222-inch, 40-grain Jet bullet, but the .223-inch 45-grain Hornet bullet was also used here. Both gave good accuracy. With continued experimenting, the 45-grain Hornady .224-inch Hornet bullet, which is much more commonly available, likewise proved accurate and is a viable option if the other two bullets are not readily obtainable.

All loads in the accompanying data worked flawlessly in the test revolver; cylinder rotation was reliable.
