"The .224 Weatherby Magnum was developed in 1963 by Roy Weatherby after about 10 years of development. It is a proprietary cartridge cartridge with no major firearms manufacturers chambering rifles for it other than Weatherby.
The cartridge design began years earlier but its introduction was delayed, at least in part, because of the unavailabilitiy of a suitable action. An earlier high-velocity .22 caliber round from Weatherby called the .220 Weatherby Rocket was based on the .220 Swift though it was unsuccessful and never manufactured.
Performance is similar to the popular .22-250 and the lesser used .225 Winchester putting it in between the .220 Swift and .223 Remington cartridges. Possibly because of the similar performance and popularity of the .22-250, this round has never gotten a very large following. Costs for ammunition and rifles for this round also tend to be much more expensive.
.22 caliber rifles are legal in some areas for big game up to the size of deer or larger. However, this cartridge is better suited to long-range varminting."
