This specific ammunition refers to a .22 Winchester Magnum Rimfire cartridge manufactured by CCI. Characterized by a 40-grain jacketed hollow-point bullet, it is marketed for small game hunting and target shooting. The “Maxi-Mag” designation highlights its magnum-level performance within the .22 WMR category, offering higher velocities and greater energy transfer compared to standard .22 LR ammunition.
The increased velocity and energy make this type of cartridge effective for varmint control and dispatching small game humanely and efficiently. Its accuracy and consistency also make it a popular choice among target shooters. CCI’s established reputation for quality and reliability further contributes to the widespread use of this ammunition. Introduced in 1959, the .22 Winchester Magnum Rimfire filled a gap between the .22 Long Rifle and centerfire cartridges, offering a significant increase in power for rimfire enthusiasts.
