224 R-C Max

Historical Notes:

The 224 R-C Maxi was developed by Don Rissi and Jack Chechowitz, both of Reno, Nevada in 1987. Most of the work was done while the two were students attending the NRA summer gunsmithing classes at Lassen College in Susanville, California. The cartridge is based on the 357 Remington Maximum necked down to 22 caliber. This provides a rimmed case with practically the same capacity as the 222 Remington, and loading data for the 222 Remington can be used with similar results, but should be reduced by 10% when starting to work up loads. The cartridge is similar to the 5.64x47Rmm, but shorter. The purpose of the cartridge was to provide a rimmed version of the 222 Remington for use in single shot rifles and pistols such as the small Martini or the Thompson Center. The originators used the 222 Remington dies to form the case along with a RCBS .357 shell holder with .002 inch ground off to achieve proper shoulder placement.

General Comments:

The 224 R-C Maxi, like the 222 Remington, is an accurate cartridge suitable for target or varmint shooting. It can cover the same use range as the 222 Remington where a rimmed cartridge is desirable. Brass 357 Remington Maximum cases are available in larger sporting good stores, and this case is simple to form without a lot of expensive dies or other equipment. There are other versions of this cartridge and, of course, the standard 357 Magnum has been necked down to 22 caliber. The 22 Remington Jet is also based on the 357 Magnum case. These cartridges are in the same class, but those made from the 357 Maximum cases hold more powder and can generate more power at any given maximum pressure.
