Safety Notes
1. Start with minimum loads and work up carefully, watching for signs of pressure.
2. The .22 CCM is not a SAAMI-standardized cartridge, so use caution when developing loads.
3. Always consult multiple sources and start with conservative loads when reloading for this cartridge.
It’s important to note that due to the cartridge’s limited popularity, load data is scarce and may not be as thoroughly tested as more common calibers. Reloaders should exercise extra caution and start well below maximum loads when working with the .22 CCM.
