The 22-6mm cartridge is a wildcat rifle round, meaning it is not commercially produced but rather custom-made by handloading enthusiasts. It involves necking down a 6mm Remington case to accept a .224 inch (5.56mm) diameter bullet. This results in a high-velocity round that maintains the case capacity of the 6mm Remington.
Use Cases:
- Varmint Hunting: The cartridge's high velocity and flat trajectory make it particularly effective for varmint hunting, including targets like prairie dogs and coyotes.
- Target Shooting: The precision and velocity can also benefit long-range target shooting, though it is more commonly used by those who handload their ammunition due to its wildcat status.
General Knowledge:
- Ballistics: The cartridge offers improved ballistics over standard .22 caliber rounds because of the increased powder capacity of the 6mm Remington case.
- Reloading: Those who use this cartridge typically do so for specific performance benefits and are usually experienced handloaders.
Since it's a wildcat cartridge, details like the exact velocity and bullet weights can vary widely depending on specific custom loads.
