.22 Remington Jet
cartridge
The .22 Remington Jet (5.6x33mmR) is a .22 in (5.6mm) American centerfire revolver and rifle cartridge. The round is known in the US as .22 Jet, .22 Center Fire Magnum/.22 CFM or .22 Rem Jet.
Development
Developed jointly by Remington and Smith & Wesson, it was to be used in the Model 53 revolver, which first appeared late in 1961. While it traced its origins to potent wildcats such as the .224 Harvey Kay-Chuk, which ultimately derive from the .22 Hornet, it was a bottlenecked cartridge based upon the .357 Magnum case necked down to a .22 caliber bullet, with an unusually long tapered shoulder.
By 1972, the Model 53 remained the only revolver chambered for it, while Marlin in 1972 was planning a lever rifle in .22 Jet. The .22 Jet was also a factory chambering for the Thompson/Center Contender and the design allowed for it to reach its full potential, having no cylinder gap and no case setback.
Usage
The .22 Jet was designed as a flat-shooting hunting round for handguns, and it is suitable for handgun hunting of varmints and medium game out to 100 yd (90 m). The 2460 ft/s (750 m/s) and 535 ft-lbf (725 J) claimed for factory test loads did not prove out in service weapons.

This brief starts where responsible research should: with the source description of “.22 Remington Jet” as cartridge. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as cartridge. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Mar 31, 2025. The linked authority identifier is Q4545200. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1961 and 1972.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
